When I look at my MCP the power comes in from bottom and goes out at top. The circuit breaker cut power for wiring in house but does nothing for wires coming into box. For that have to go out and up plug meter. Putting the MCB outside before the MCP makes good sense. Now all power cut out side the house. At least that’s way I see it? My brain wired more mechanical than electrical…
beings I was dinosaur mechanic…
