It is quite funny. On the one hand, there are single insulated conductors carrying 100A (?) of current that are bolted directly to a wooden substructure without any additional protection against touching. On the other hand, you are using metal conduit for the new wiring. Meanwhile in Germany we use a lot more plastic stuff that does not require drilling into metal, lockrings and that is insulated in itself...on the other hand, running 5x25mm² as a multi core conductor certainly is less fun than what you are doing with individual single conductors...

Older French wiring is something else though! Braided sheath cables with push button switches just hanging from the ceiling which make your arm tingle when you touch the cable. Spurs installed on spurs, with no earth connection. Cables spliced with a choc block connector under enough tension that the connections pulled apart when the temperature dropped.

Interesting video 2x👍 I work for 6 months in a power station, that was truly "widow maker" power. Parts of site you needed special overalls with no metal. You could feel the power just walking past outside the room.

Appreciate the shoutout, Cory! Great to see our job management software is benefitting your business!

Pretty sure those old federal boards arent even classed as protective devices anymore just isolators. Always pray they re-engage when switching on/off. Had a few not turn back on after a shutdown

Worked on a Coherent Everlase CO2 laser that was a literal widow maker. At its heart it had a large 3 phase transformer that took 480 in and put out plus and minus 40kv with filter capacitors that were fed to the lasing tube. It was current regulated on the ground side with 4 big glass transmitting tetrodes. The widow maker part was the mirror mount that needed adjustment occasionally was floating at 45kv at whatever current the transformer could source through your body. The laser had to be running in order to adjust the optimum alignment. Working on it was a bit of pucker factor, to add to it, the tubes were supported on a large granite slab so it has the tombstone built into it. Was very relieved when we retired it and upgraded to a Truamph slab laser that used RF. 😂

FPE Electric... = Fire Prone Equipment (at least here in the US.) The "Stab Loc" line is extremely dangerous.. and there were thousands of the industrial breakers that were prone to failing by emitting smoke, sparks or exploding..and FPE's solution? They issued stickers saying don't touch it, and call a 1 800 number....🙄 I personally worked on several Stab loc panels, and a few of the industrial panels...and hated them with a passion.

Whether you did or didn’t know Cory. Those old black cutouts / fuse holders can be made from a material that becomes phenolic overtime (degrades and becomes conductive) it’s not been uncommon for people to have tingles from them. Meter fitting companies etc generally use a Martindale VT7 to check these. I can send you one if you like ?

Hi Cory great video as always. Would this need a Type 1 Surge Arrester on account of Over-ground power lines? I would assume the HV lines are over-ground as well as LV.

Henley blocks have single insulation outside of the enclosure, they also have black tape covering one of the entries still get a finger or tool inside it, they are also upside down. If they only needed three ways they should of swapped it for a three way Henley block instead of taping over one way.

Some curious things I realised, working for a Dutch DNO, is that in our part of the grid, we kept the old UK colour coding, i.e. red, yellow and blue (the consumer side does use brown, black and grey). One other thing is that - as the story goes - these colours were sometimes painted in the wrong order on the bus bars inside distribution stations. The pragmatic approach was not to redo everything but just supply either a right rotating or a left rotating field to the customer. From there on it is up to the electrician of the consumer to wire the devices in the right rotation. So, when changing a meter, we have to check the rotation twice to make sure before and after are the same, it's easy to swap wires (and actually simulated during training and examinations). Some devices won't work on the wrong rotation, but some will just go the other way around, as you mentioned, possibly damaging or destroying things.

Question from Norway: Why are not the meter box and main fuses from the grid inside a enclosure?

the other guy said it first but henley blocks should be facing downwards or maybe side ways, i think its something to do with IP rating? not 100% tho..

You got that easy, able to turn it off, a luxury. I was a sparks on the docks in the late seventy's. It cannot be turned off as it costs a very lot of of money. Buss bar chamber live 2000A fuse behind it. Drill the solid copper bars, connect up the cables with nuts and bolts, that means one arm is up behind the bars with a spanner and a bit of tape round it. The same for the bolt head at the front. Put lid back on and jobs a goodun. I hardly ever worked with the power off unless the crane or whatever was down for maintenance.

Can't work out why the db wasn't terminated before the bus connections? Would have been much quicker?

what I don't understand is that Makita's best combi drill is more expensive then Milwaukee's and has a much longer service life yet people still think Milwaukee is better. I'm using a Makita 3/4 impact wrench that is still going strong for 8 years of daily abuse that has outlasted 3 Milwaukee 3/4 guns. just why are people defending this TTI crap. the only Makita product from their top line that I have to replace so far is batteries after 5 years of hard use as a agricultural mechanic. ive been at it 14 years and the batteries do wear out unsurprisingly. There is one exception... The torches and multi postilion lights fall apart buy the Makita top of the line whatever tool you need and it pays for itself

I once warned a supposedly senior electrician to turn off and meter the 440vac before removing starter arc chutes. After his first grab and shock, he opined that was just static. Then he grabbed it a second time. I told him I was going to shut off the breaker while he recovered. A different time, a three phase disconnect was positioned off, but one of the switches broke off the actuator bar, leaving one phase still hot. Yeh, I also ohms check the meter leads before every voltage check. "440 don't like to let go of you." is the folk saying.

Careful with the Sharpie. You don't have a 5 inch long insulator, you have a thinwall plastic tube with a liquid ink wick up the middle of it. The vapour aspect of the ink and solvent is unpredictable and may depend on the colour of the ink but I know from experience that sticking a Sharpie in a HF radio amplifier with 1500VDC on the top of the bottles is a bad plan and caused a hell of a lot of paperwork and several clipboards turned up. It broke down in a split second and all our bowels leaked out.
