![]() ![]() I believe this is what OP has, obviously a different brand/style, but same principle. I can go on further in explaining it, but again, this set up is completely safe.Īs for the people saying that that breaker isn’t tested to be there? Your little 20a breakers inside are attached to a bus that has 100+ amps of potential power? What’s the difference? They put in the 125a to feed interior and left you some room for other stuff in the future. No reason to have a 200 panel in a house, costs too much in wire size and equipment for contractors to install one and your typical house doesn’t need that much power. ![]() It’s rated for up to 200 amps, doesn’t mean you have use all 200. I only have the one 125 breaker feeding my interior panel, the other space is open for the future. The higher the number of amps, the more electricity you can use in your home. The amperage (amps) referred to is a measurement of electricity. The most common sizes in residential use are 100 amps, 150 amps and 200 amps. My brand new house had the same meter/main combo. The main disconnect fuses or breakers act as safety barriers in the case of an electrical problem or overload. As for the 30A, could be feeding a well pump, sub panel, RV charger, you’d have to look around to find what 30A piece of equipment your house has that’s not being fed out of your interior panel. That 125A is your first means of disconnect for your interior panel and as long it as that panel is rated to be protected by an 125A OCPD (which it likely is) then it’s fine. ![]() Meter comes in, feeds a piece of bussing, those breakers are attached to the busing and feed your house. It’s a meter/main combo? Those breakers don’t have to be 200A? It’s completely safe as is. ![]()
