    They must be protected at the point of supply. Interpret that how you will, but it's more specific than 'adequately.'



    Having reviewed the definitions, I agree with you unless or until someone...

    That service doesn't have any feeders.

    I don't get what's difficult to understand about that.

    Yeah, but then ggunn said that a seventh could be installed.

    Curious if this panel has any instructions which speak to whether more than 6 breakers can be installed without having a main...

    Sure it does. The feeder and the branch circuit are different circuit conductors.

    If all you do is wire cheap toggles and receptacles, then yes, solid is good. If you're running mostly NM and not pulling through conduit, then it doesn't matter. By and large I don't think...

    Missing piece of deadfront at the top?

    And, to my point... Is there supposed to be a main breaker there?

    No, because each circuit - the feeder and the branch circuits - are properly protected at their rating and point of supply.



    All good. Although it makes no pratical difference in most...

    Again, you'll need to look at every motor or other appliance on a case-by-case basis.



    Okay, that clears that part up. You still may have more than one option of how to move forward, such as...

    No, the 30A is for a sub. If the two breakers were both in series on a branch circuit and the 50A is only for GFCI then I wouldn't say this is wrong. But the 50A is the branch circuit protection...

    I don't know why you say 'struggling'. I think 'at the point of supply' is pretty clear. The point of supply for the branch circuit is the sub, not the feeder.

    240.21



    Emphasis mine. (A) thru (H) provides nothing addressing this.

    A short or overload on the branch circuit can trip the 30A sub breaker before the 50A branch circuit breaker, and shut...

    You're so far off on the 'single busbar' I can't even follow what you're thinking.




    You have it exactly backwards. Look up Ohms law. A heater at 208V will heat up less than at 240V. A...

    It might be worth noting in this thread...

    Conductors 8awg or larger in a raceway have to be stranded.

    You need the secondary to be a wye or your Tripowers won't operate. Confirm that with SMA if you want to be sure, but that's the connection listed on the datasheet.

    I'm assuming they are...

    Most of the panels I've seen would take at most six single-pole. The Square-D I mentioned is the one exception I've seen.

    I guess the real gist of the question is; how often, if ever, would...

    I've run into quite a few different service panels of an 'MLO' type. That is to say, they are designed to have multiple service disconnects, a.k.a 'handles'. ...

    That's not the service. That's the utility's distribution feeder. Try to keep terms straight. The existing service, as you told us in the first post, is 240/120 split phase. You are considering...

    Well, that sucks.
