Obviously, I can't cover everything, but if you have questions, please do ask. Today we will be reviewing how an American electrical panel works, what cables we use, how portable generators are connected to the house, and how to tell whether the utility (street) power is back on. Covering two major electrical building cable types used in USA: NM ("Romex") and AC ("BX"). Finally, showing a power indicator that I assembled to monitor both the utility ("street") power supply and the generator power supply and consumption.

Hi, Zaur! I agree that ferrules have to totally replace tinned wires because there're few problems with them. The first problem is that a tinned end of a stranded wire loses its flexibility and there will be always crack or fracture (when you bend it) at a place where tin ends. This could lead either to breaking the wire or to heating up it and sequentially to a fire. The thinner the wire the higher chance of this effect. The second problem is that a tinned end is deformed under pressure more easily and not really useful for the second time. So when you tighten up tinned end and there is need to disconnect the wire you have to cut the tinned end and solder the wire again. And you'll have to do it every time when you disconnect the wire and connect it again. And if you didn't make provision for sufficient length you'd have to replace the whole wire after a while. Ferrules are more sustainable to these effects.

Vasiliy, those are great points, totally agree!
Nice video.
Where did you get the panel display Volt/ Amp readouts ?
@@Gruntled2001 The panel mount volt/ amp readouts are not sold at Home Depot. Looks like a Newark item, but not sure of the manufacturer?
