Help would be greatly appreciated from anyone with a working understanding of tap rules. The situation is as follows:
It's a single phase residence with a 400A service. There's a fused 400 amp disconnect by the meter pedestal. Inside the home each 400A wire is spliced with a pair of 200A wires. One set goes to a 200A fused disconnect for hot water baseboard heat, the other set goes to a 200A MB distribution panel. I'm assuming the 200A wire is allowed to be fused at 400A by a tap rule. The 200A wires are under 10 feet long.
My question is:
Am I allowed another tap on this 400A wire to another 200A distribution panel if the load calculation comes in under 320A?
