Sure, the fuse disconnect from the meter was replaced by circuit breakers, but the sub panels themselves have no main, lugs only. So the circuit goes from the main panel breaker to the sub lug only. Just curious if the replacements subs need mains or main lugs are fine as a replacement.... Main lugs are fine at the subpanel as long as the feeder is protected at its source by a circuit breaker sized to its wire size. Perhaps you could provide a small diagram of the service conductors, the meter, the disconnect, the breakers, and the feeders? Cheers, Wayne |

Cheers, Wayne Sure enough Wayne. -----Line from pole-----meter------Main Panel Lugs only------55 Amp Breaker in Main Panel---------Sub Panel 1 Lugs only | | --------55 Amp Breaker in Main Panel---------Sub Panel 2 Lugs only Another question, I guess, is what is the max sub panel feed I can have and not need a Main Breaker installed in the main panel. Or, is there a cummulative load that would require the addition of a Main Breaker; like if I add a 3rd panel on a 3rd 55amp breaker. TIA! -A |

TIA! -A If there is not a 200 amp disconnect at the meter equipment, you are limited to six disconnects in or at the main panel. The sub panels do not need disconnects in them unless they are in separate buildings, garages, out buildings, etc, but if the main panel is larger than what will hold 6- double pole breakers, you need a main disconnect to use those spaces |
