But the cheapest most practical way to get that is to use a box with a main breaker. To be more precise, you need a main disconnect switch. As well you should! You are at liberty to get as large a panel as you want. This also ties into the "spaces" problem because I gather you were feeling stifled with only 8 spaces. It's a "limit" thing, not a "mandatory match" thing. So 125A or even 200A is perfectly reasonable. You wouldn't run 60A on a 60A box, would you? Of course not, you want some safety headroom. The same applies to service panel amp ratings.
Yeah, you'll want the 115 or 130 mph tires I think :) Suppose you lived in Nevada where posted limits are 80 mph. You wouldn't drive 85 mph on 85 mph-rated tires, would you? I mean "space" not "circuit" - you see a lot of 20 space/40 circuit panels - that's only a 20-space. All of our panels here have plenty of extra space (except an 8-space Pushmatic that's a nightmare) and that's the way we like it. You need 8 spaces? Consider nothing less than 24 spaces.
But the regrets and unnecessary expense when you run out of spaces is a rather expensive affair.Īs such we very strongly recommend you wildly oversize your panels. The out-of-pocket cost for a larger panel is very small (especially when you consider other factors, as we're about to). Listen, there's always a future project, there's always another load. Your box definitely should exceed minimums in this area: Number of spaces.
