Having worked in fast food myself, it’s not surprising at all that the restaurant kept operating with the broken exhaust fans even though you told them not to. I once worked somewhere that had the AC fail on a record high day (like 112F, which is abnormally hot for the PNW). I was in the drive thru, which was essentially a green house attached to the building directly next to all the warmers and a large freezer that was all contained in the drive thru (I.e. the condensing unit was in there too). At one point, it was 125F in the drive thru. Management wouldn’t allow us to open the doors because of health code, and also wouldn’t close the drive thru even though we were about to pass out. They didn’t care, they were home in their AC-ed house. If I wasn’t a dumb teenager who was desperate for the job at the time, I’d have at least closed down the drive thru, if not the entire restaurant. No customers wanted to stay in the building anyway since it was basically cooler outside. I’m glad nobody had any medical issues as a result, but I almost wish someone did because it would have served the management right to get stuck with the expenses and lawsuits related to it. Restaurant management, particularly franchised restaurants that have managers with no ownership of the restaurant, care only about money. The employees are basically just slaves. I’m sure management of this place didn’t give a second though about the kitchen employees inhaling smoke and oil vapor for hours as long as they didn’t have to shut down the restaurant on their shift.

Hearing that they kept cooking while their exhaust fans were down, reminds me of a tidbit of building code from Germany: you need to install solenoid valves into the gas main of kitches (if natural gas is used for the oven etc.) that are interlocked with the exhaust system. If correctly installed and maintained you can not cook if the exhausts are down. It is not necessary for kitchens that run solely on electricity though.

There's also a similar-kind rule for household fireplaces and exhaust systems. You're not allowed to have the exhaust running without having a window open. Otherwise the exhaust will cause an underpressure, pulling air through the chimney into the room. And when the fire is on, all that toxic carbon monoxide will now be in your room. Pretty interesting how things unsuspectingly may influence each other.

I'm a chef myself and I had to work in a kitchen without working fans once. I told the manager/boss that I'm out when he's not fixing these fans. It's been a room temperature of 43°C (in the coldest area / in the plating area at the front it's been 52°C) - way too high for any human being to be in there for at least 8 hours... he called the fan company right there and the next day they were there to tell the boss that he needs everything replaced because it's been so old, there are no spare parts available. This place was closed for a week "due to important renovations" and after that we had a maximum of 34°C in that kitchen - way better and for a kitchen these temperatures are normal.

Chris, your propane danger sign reminds me, we have one on our propane rack at work that reads, "No Smoking Propane" , with no punctuation. Apparently one could smoke anything but the propane.

Another guy said that if one could keep it in a pipe, the fuel would smoke the one lighting it.😁

The last thing I want to do in make a hole on the top of a electrical panel or box if I don’t have to. Instead, loop around to the bottom instead. The rare times I do have to come in from the top, I’ll use sealer to better seal. I just had to replace a PLC because of the power coming in from the top. I opened the box with it filled with a bunch of water. Something that came that way. I used sealer on the fitting and replaced the PLC.

I have learned from some old electricians to always try to pull the wires from the underside of the disconnect. This way there is less chance of water entering the box. Also, European style outdoor breakerbox can be used with a breaker as a disconnect switch. This way there is a protected disconnect. And it will be like each fan is on a seperate circuit.

Many of those switches actually have a small punch-out area that you can punch out to let water out. That's useful if there's a high risk of condensation inside the casing.

When I was in high school I worked at a restaurant where the exhaust fans went down and they kept cooking. The fire sprinkler went off and flooded their kitchen. The restaurant went from nearly full to nearly empty over the course of 10 minutes once the fire alarm started going off (there was never a fire, so we didn't evacuate, but people understandably get antsy when an alarm is blaring). It took them a few days to clean up the mess and get the kitchen fully working again.

Everything in the reach-ins had to be tossed as per Health Regs. It was considered contaminated and unsafe for sale and consumption. Then the coolers all needed to be scrubbed and swabbed to be sure no suppressant residue was in the trackways for the doors.

When putting stranded wires into a screw down fitting, aren't you supposed to use hollow ferrule over the strands? EDIT: Some screw downs have a flat plate the screw pushes on, not the screw tip right on the wire... If this switch has that feature, then bare strands are OK. I see both kinds of screw downs these days, and keep ferrules in stock for the times they are needed when we are doing electrical work. It would be educational for the viewers if you could cover this detail. We also use dielectric grease, smear it all over the bare wire before insertion, that produces a moisture and oxygen barrier to keep corrosion next to zero over the passing of time. New switch looks great! END EDIT

So what the one fan was exhausting, the other was pulling the smoke back down into the kitchen.

Hello, In Australia we use a lot of the plastic style isolation switches. I would have put both cables into the box from the bottom, much better form maintaining IP66 keep in mind 100mm or 4in of rain per day is the norm in summer. The ansul fire wire I have seen comes in a few different fuse temps, 350deg C is the most common but will change to meet the fire risk level determined by the fire risk assessment and the building code.

USA knife switch style isolators/switches are much the same as what we used in Australia in the 1930's; over here top entry into an isolator is banned due to the possibility of water ingress. Plastic rotary isolators are far better than the crap metal ones I see in most US videos

You probably meant to say that Black, Red, Blue was the normal sequence, not Black, Blue, Red. We call it the Line side of the switch. Always enjoy your willingness to explain why you are following certain procedures.

Two things.#1 The standardized NEC Color code for 208v~ is 1-black 2-red 3-blue. And Brown, orange, yellow for 480v~ and obviously the feed coming from the power source was counter clockwise, that's why you had to reverse it in the switch. #2 you should always try to put line side voltage to the TOP of all switches and disconnects. Although it doesn't matter for some types of switches, it does for disconnects. And it's just good practice.

Yeah it's called uv resistant clear tape.

Great vid and great info ... Thx for posting Bud ...

I would always try and fit both conduits to the bottom of an isolation switch reduces water ingress greatly

My dad accidentally tripped the fire suppression system in a Coney Island restaurant a friend of his owned by accidentally cutting a cable that activated it. Fortunately it occurred while the place was undergoing renovation before opening.

Many Fire suspression systems have a "dead-man" switch type circuit. If any part is damaged , cut, broken, etc. they go off. Can be very important to shut off the system , before you unplug or replace any part of it. I know cases where people disconnect one sensor to replace it, and POOF! Baby powder everywhere. LOL Actaully it is some type of Halon. But it defintely makes a mess and coats everything, and is hard to clean up, much like baby powder. It kinda sticks.

I dunno about plastic boxes out in the Sun... Sounds like a recipe for a cracked/broken box... It'll be cool though! ;-)

Very interesting on the fire suppression info etc. Thanks Chris.

Love the Simpson 260 on the set behind you my favorite tool to check armatures.

The things you have to go through crazy stuff awesome

Thanks for the tighten, loosen, tighten.

I was talking with some fire men, and they had shut down a popular restaurant when they where getting food for lunch, they drove past it, and there was fire shooting 15 feet above the roof out the exhaust fan. The cooks where inside making a lot of lunch for the crowded and popular place. The Fire Captain found and pulled the plug on the automatic system, while two firemen went to the roof to put out the flames. The auto system did it's job. The place was closed for about 4 days to clean up the fire suppression stuff. Most times it is like 200 pounds of baking soda that is pressurized to about 400 PSI in a huge tank, about a foot in diameter and about 4 feet tall! I would guess the fuseable link will melt around 300 - 350F. By 500F, the grease on the walls of the air ducts would already be ready to catch fire! The rooftop fan was covered in thick grease, not cleaned once a year like required by local fire code. Many fines later, and they could open again, with a inspection by the Fire Department on the one year anniversary and again 1 year later. All of the food that was exposed to the fire stuff is tossed, along with cleaning the fryers and every square inch of the kitchen.. The floors where pretty bad too. I think the Health Department found warm refrigerators and other problems too. The place you where at, probably needs a good air duct cleaning too. Maybe even check the grease trap on the sewer line, they might not know they have one.

I like the 1 arm Bandits. Reminds me of my trip to Vegas.

If those fire suppression systems use the same powder as you get in extinguishers, that would have bin a sight to see. And hell to clean, that powder travels everywhere. Their kitchen AC might also need a good cleaning now, I guess it sucked up lots of grease in those 2.5hours

Kitchen fire systems are NOT dry chemical, their supposed to be wet chemical. Dry chemical was phased out in 1996 when cooking with vegetable oils. Dry chemical was used with animal fat oils.

@@richardroy4764 Ah ok, thanks for the info. I imagine you still get a mess but probably not the dust storm

when you mount conduits to boxes, that are mounted outside, never run them through the top... Water WILL find its way in... ALWAYS! Go to the bottom and drill a small hole on the bottom as a emergency drain! And check, if the products are UV resistant. If not, the plastic will get hard and crack. And i dont know, how you handle this in america... but we in germany clamp on core end sleeves on flexible wires.

We're lucky with our kitchen in our corporate building. 6 month ansul pms and hood cleanings. We inspect the exaust equipment quarterly too

Questions : Why go from motor to top oof the switch box? Why not the side of box? Idt refusing potential for woter ingres.

I had a fusible link in a fry vat hood let go one day during a lunch rush. No fire but for what ever that link just decided to do its job. It dump the system. I had to call for the hood system to be serviced. While waiting for them to arrive, I drug the fryers back to the back room and cleaned out the fryers. That was a four hour job that was not fun. I'm lucky. That's the only time I ever had one dump in 43 years of food service employment.

Plastic or specifically pvc is very common in the rest of the world for electrical. Cheap to manufacture and doesn't rust and corrode outside to the degree that metal does.

those conduit nuts are fairly soft metal. I never worry about which screwdriver I'm using, as long as it's a flat head. they wont damage the hardened steel of the screw driver

You don't have to stop cooking, but that's a lot of beer and fries to cover the costs associated with being closed for a week and all the other cleanup, repairs and inspections.

The cost of cleaning, inspecting, testing, recharging, further testing, and recertification of an Ansul system that has been fired would amount to a considerable chunk of change. Plus you could wind up with a bunch of different jurisdictions' inspectors nosing around the entire place, trolling for any and all code violations in the facility, further adding to the repair bills that will ultimately make the managements' heads explode.

Thanx for sharing!

5:33 - If you use your ‘channellocks’ to tighten that piece of the seal-tite connector to just beyond hand tight you can be sure of a good seal with low chance of vibrating loose. That technique works on metal and plastic boxes. 9:02 - The low voltage three phase colors are Ba, Rd, Bu here in Florida. Not Ba, Bu, Rd. Interesting!

North and South Carolina, Georgia also Black Red Blue for 120/208,240V and Brown Orange Yellow for 277/480V applications. I know as far as the NEC there is no hard and fast rule for the current carrying conductors.

Good work. That switch looks nice.

If it was an option, I would have put the switch sideways so the water would not go directly down into the box in the event the conduit connections break again.

Usually it's recommended to have all cables entering from either the side or the bottom, with drip loops to stop any water getting in via the conduit. You can also drill a hole in the bottom of the enclosure so that any water that comes in can get out easily.

It could have been at least been a week before they got the people to come out to get certified and they would more then more then likely been fined as well for putting the public in dangerous conditionings as well as the staff, adding up to thousands of dollars in fines. I have seen it happen before

You say don't cook you mean it, great repair

In Australia we twist the conductor strands before terminating into any terminals. it helps individual strands from breaking. Better would be crimp ferrules as well of course. Bottom entry of conduits as well.....

Very unlikely that it would ever occur, but the grounding wire should have enough slack in it so that it will be the last one pulled out.

Those Fire Sytems be easy money for those who carry the License and Insurance. Just a fancy mouse trap for most exhaust hoods of cooking appliances. Government and Insurance Companies force the people in Michigan to get their Fire System checked and signed of every six month.

Here in Tennessee the government doesn't stop there, they milk the fire installers/tech companies to. They require several thousand per year license fee and they require continuous education units, special insurance, ect. You end up with a huge overhead and giving up a bunch of time for the CEUs. It's kinda funny though, HVAC doesn't require a license here.

@@Bryan-Hensley Some Restaurants do need 6-month service and even more for Greasy Spoons and Chinese Restaurants. Churches, Schools and Catering halls only NEED it once a year if that and 6-month service makes them prone to failure due to Tech Error. That being said the fact is if you want to play the game you have to pay the Racketeers.

Thanks man!

I know exactly what the thought process was for the restaurant. "This idiot is telling me to shut down on my busiest night of the week. I can't afford to do that!" Not understanding what the potential consequences of that decision could be. Being shut down well into the next week if the fire suppression system went off and the clean up and the inspections that would need to be done to reopen.

Just FYI.. The 4" or 5" Knipex cobra pliers work really well for those box fitting nuts.

Nice work Chris.

The earth should always be longer than the rest of the wires in case someone or something pulls out the cable, that way the last wire to come loose is the earth. At least that is what I was taught in tradeschool in Iceland. Having said that, I love your professionalism. You can only give them information, but what they use said information for is out of your control.

Would it not be better to drill both holes at the bottom? This way you reduce any chance of water ingres through the fittings

Good stuff Chris

You keep doing what you do and you shouldn’t have to explain to all the keyboard safety experts out there…. You do amazing work

I personally always avoid putting any kind of a connection to the top of the box the side of the box last Chance water getting inside the and if water did come in through the side of the box minimal
