Hi Everyone,
I have a renter that is utilizing one of our flex spaces as a large dressing room. They need a lot of power for hair dryers, steamers, clothes irons for wardrobe, etc. I have a 200A disconnect with cam-lock connection in the room. They want to bring in a 400A Lex distro and only utilize the 10 Edison 20A circuits on it. Normally, visiting companies bring a 200A distro for this 200A disconnect, and that makes things easy. I'm initially concerned that the amperage for this distro is rated significantly higher than the disconnect, but only part of it is being used so that negates most of my concern. The model of the Lex Products distro is PH400A3BNJ-2ACC2C-1050.
If the 10 circuits are pulling 20A each, that keeps the total amperage right at 200A. Does anyone know if a distro that has multiple outs like this one has some kind of internal limit or a kind of sub-breaker for each part (a limit for the Edison part, a limit for the NEMA, etc)? I want to ensure 20% contingency and only pull 80% of 200A. For some smaller distros that I've used, say a 50A distro that has 6 circuits @ 20A, it seems very possible that higher draw applications would easily trip the circuit feeding this distro if each circuit on the distro is under 20A but collectively the distro is over 50A. I want to avoid any and all trips and overloads, whether it be 50A or 200A. I will ensure power is evenly distributed with other sources in the room so that we don't use all 10 of these circuits on their distro, but in case someone see an empty plug on this and plugs something in to all 10 circuits anyway, I want to know what would happen.
I've called Lex Products to answer this question and they said they'll get back to me as I can't find the model's manual online. Thanks in advance for your thoughts and ideas.
