EE programs tend to focus on electronics, not electrical systems. But learning how house wiring works is a simple book away. But be careful - unlike electronics, house electrics can kill you.

On the other hand, electricians have weird gaps in their knowledge. If I ask them to do something slightly out of the ordinary, this becomes apparent. For example, none of them understand inductive coupling, or even know what it is. When I ask them to do certain things to avoid inductive coupling, they give me this indulgent smile, and do what I ask, although it's clear they don't understand why.

I eventually wound up doing the low voltage wiring myself, because I simply couldn't explain to them why you don't run low voltage wires through the same holes as the A/C wires. One of them tried to run a 12VDC wire in 25 feet of conduit with a 120VAC wire.

They also simply did not understand how generators worked, and botched up the wiring for mine.

It's the same with roofers. They have no idea what galvanic corrosion is, and will invariably use the wrong nails for anything metal.
