What are your thoughts on the '08 nec eliminating the 42 circuit restriction in a panel? I saw a 70 circuit Square D panel in a slide presentation the other day.

Is it 3 phase or single phase??? I have never seen a single phase over 40 circuitsiwire said:I actually work at a factory that has a Square D NQOB 225 amp 54 circuit panel being used as a lighting and appliance branch circuit panel, it has been there since the 80s. I have no idea how or way it ended up there.

There's a 40-space/80-circuit panel, too. Everything that doesn't meet our present limitations begins with a C in the model number. Obviously, it stands for Canada. I wonder if it means we can't order one at all.iwire said:Check out this pdf, it shows indoor single phase load centers with up to 60 full size spaces or up to 80 poles using minis. :smile:
I have installed a number of the 54 circuit Square D panels. My use was for heat trace panels where we use breakers with an "bell alarm" option. (a bell alarm option closes a set of contacts when the breaker trips but not when it is turned off) That takes up a full space but does not count as an overcurrent device so my use was still in compliance with the NEC. These panels were readily available from the local Square D distributor.I actually work at a factory that has a Square D NQOB 225 amp 54 circuit panel being used as a lighting and appliance branch circuit panel, it has been there since the 80s.

Yeah, 10.steve66 said:Just think how many tandem breakers we can fit in on of those 70 space panels. :grin:
