What is it with sub-panels?:twisted:
I got two main service panels with a sub-panel. Three wires feeding sub-panel and ground and neutral bars are bonded. The 100 amp feed to the sub-panel has a marker on the wire that says gen-set and the 100 amp breaker on the sub-panel attached to the feed says sub-panel feed. This is on the left side of the sub-panel. The right side of the sub-panel has a 60 amp breaker labeled portable gen. receptacle. There is a twist lock receptacle in the garage presumably for a portable generator.
I can’t tell of course if they intended for a genset with a transfer switch to be inserted between the main panel and sub-panel (this would seem to make sense). There are two boxes on the side of the house about six feet apart that have what appears to be about #6 AWG wire in them but they are not connected together in anyway. You would think that without the generator, they would need to connect the ends of these wires together temporarily. The receptacle marked as for a portable generator doesn’t seem like a good idea. If your using that, what happens when commercial power kicks back on? Do portables come with some kind of sensor so they kick off when commercial power is restored.
