Well first, I stood back and took a deep breath , and just soaked it all in. At first, I thought too, that this just might be over my head. (I don’t pretend to be an electrician). Fortunately, though, I was alone on this inspection (homeowner passed away and my clients are not in the area yet, business transfer) so I decided to just take my time, go for it and make it a learning experience.
Basically, I just treated it like any other inspection and focused on one component at a time. I actually did open up every panel. I don’t wear a watch when I’m on an inspection, but I think that I spent about 1 1/2 hours just looking at all of the electrical panels. Actually, the big ones, though they look intimidating, are just big metal boxes with 2 big fuses in each of them, with a throw switch (yea, i know, that’s simplistic). And the several panels of relays, basically made sure they worked, no scorching, no clattering, etc. I used to sell spas/hot tubs and worked on them some. The relays were pretty much the same as I would see in older spa packs. All the sub panels I just treated like any other sub.
I even opened up the main disconnect. As you commercial guys probably know, to open up a panel like that, you have to throw the switch off. I thought about that for a long time and considered what, if any consequences there might be to shut off all of the power to the house, but decided what the heck, in for a penny in for a pound ( or whatever the saying is). I put on my head lamp, turned on my second flashlight, and went for it.
And I lived to tell the tale .
