Home inspector is a scam , they don't warrenty thier work? They take your money and run, just call your local electrical company to do this.
Very comprehensive inspection. I am a recently-retired professor of biology. One thing that I had access to back when I was still teaching was a lab safety inspection checklist. I used the checklist in preparing for scheduled lab inspections. I am wondering if electricians and homeowners would benefit from a home electrical inspection checklist. Just a thought. It would be fairly easy to generate from what you addressed in your video. Thanks for sharing your knowledge.

Unfortunately, some of your information is incorrect. When pointing to the neutral busbar you said ‘fused neutrals’ were permitted prior to the ‘96 NEC. The term fused neutral is not applicable to what you pointed out. Secondly, multiple grounded conductors (most of those wires are not ‘neutrals’) are not permitted under a single busbar terminal). Although not added to the Code until the 2002 edition, the listing, and the ‘label’ within the panelboard would have indicated if more than ‘one’ grounded conductor was permitted, which it wouldn’t. Also, a ‘green’ insulated wire would not normally be found between the meter socket enclosure and the panelboard. The grounded service conductor would normally be bonded within the meter enclosure, in addition to a bonding bushing and jumper on either end of the nipple connecting the meter enclosure to the panelboard.

I'm from the US and watching CJR do y'alls inspections is interesting and confusing. I think where the major difference is we are mostly 120vac where I understand yall are 240vac. The consequences of a short in 240 is worlds different. Still trying to figure out rings, spurs, mcd's and rcd's. I finally figured out the testing gizmo is just a meggar, a fancy expensive one. Here in my home, I have a 200amp "consumer unit". I want a bigger one so I can have more 240 outlets in the garage for a welder and an air compressor. No testing is required by the NEC in residential that I've ever read.

@@kevinwalker4623 forget about rings, only dinosaurs are still installing them in new builds, and in exsisting dwellings they're a constant source of headache. RCBO is a GFCI from what I understand, difference is we do it at the DB so we can protect the entirety of the cable as well as outlets. RCD is an older version of GFCI that covered a couple of circuits, problem was a fault in any of the circuits resulted in a loss of alot of your circuits until it was reset, and if the issue is bad enough it wouldn't reset until you found a fault

@@kevinwalker4623 also our testing is to determine a multitude of things, earth fault loop impedance (make sure our ground is actually connected right the way through and it adequate to actually carry the fault current sufficiently to 1. trip breaker within a given time and 2.carry the fault current without also causing fire. While megger is the brand CJR uses there is others, but his tester same as mine will carry out the 4 main tests we care about, earth fault loop impedance, ring continuity, RCD/RCBO tripping times, insulation resistance
The placement of the carbon monoxide detector would be lethal to the occupants if a CO emission began accumulating the deadly gas in the home, CO is heavier than air and will not be detected until it reaches the height that the detector is placed. Good call on using the plastic pen in the breaker box, I'm nervous when working on putting wire into a breaker and securing it with the screw., I've shorted them before. I don't care how much less aluminum wire costs, copper is the best for home use, it's all there is here in NY State.

The CO alarm is suppose to be few inches off the floor not that high. By the time CO alarm goes off, the occupants Let's say sleeping on the bed would be dead. The CO gas is much heavier than other gases or air and starts to sink on the floor and built up. The CO alarm, I recommend to be installed no more than 24 inches off the ground on the wall. I don't understand why he didn't call that as a defect.

From the video, it’s hard to discern if multiple cables are entering the cabinet through a connector or a raceway. If it’s a nonmetallic sheathed cable (Romex) connector, some jurisdictions would consider the installation an NEC violation because the connector is not listed for multiple cables. ‘Bundling’, as you refer to it, describes a failure to maintain separation of cables, but it’s only an NEC violation if the length of the ‘bundled’ cables exceeds 24-inches.

At 5:10 You use the term "fused Neutrals" This is not the correct term. A fused neutral is a dangerous condition, typically found in knob and tube wiring sections. You are referring to multiple neutrals under one lug. I am not being critical, but using the wrong terms can be confusing for all involved.

Nice job but OSHA doesn’t care if you’re making a video, proper PPE is always required inside the arc flash boundary. I’m a retired electrician and we all had to learn how to do a lot of things we didn’t think were realistic when all of the arc flash regulations came out. I thought they were nuts in the beginning but when I moved over into power distribution, substation, and breaker maintenance I got to work with really good electrical engineers doing arc flash studies and trip device settings I got to see clearly how it all works. And yes, even the little 120/240 breaker panel can be extremely dangerous depending on the coordination of the over current devices and the power source. We found some panels that beyond class 4, they were prohibited for energized work under any condition.
