I’d say I’m pretty capable at residential electric, but I have very little knowledge when it comes to these in-home generators. Is it typical to have so many wires packed together in such a tight space like at the bottom of this panel? I know you can’t stack too many wires directly on each other for fear of lowering the capacity on the circuit/heat issues. Wouldn’t packing all these together in this flex conduit do the same thing? Just looking for opinions. Luckily the homeowner okayed me to use an old junction box for his bathroom wiring. Otherwise I’d have to fish a wire through all of this mess for two outlets.
