Re: sub panel fed from sub panel

Steve, I don't mean to be the bad guy here, but
An electrician that doesn't know what they are doing is scary, but one that THINKS they know what they are doing is WORSE
Which category do you think you fall under?

Of course you can feed a panel from a panel.
 
Re: sub panel fed from sub panel

I know it looks bad, but this one has nagged me for a while, and I haven't found a reference. Because I didn't find a reference against doesn't mean that I could do something. I know that a sub feed from an existing subpanel would just be another load. I just had a problem spelling that out to someone using code references.
We had a discussion about different rules in different communities in our area. This one was cited. I couldn't give a code reference answer. I don't even know yet if this truly is a rule in that community, I thought I would ask first. From there I would go to that community next.

Thank you for pointing out the discrepancy between my question and my signature, but I thought that finding answers on items we couldn't find answers for was part of what this forum is for. Otherwise, we would just be bragging about our electrical work. An Electrician that doesn't ask when he doesn't know is an idiot.

Generally, yes it does. If the NEC does not explicitly say you can't, then you can. Some reason needs to be applied to this rule. I don?t think the NEC forbids you to rob a bank :eek: , and there are other things that it doesn?t tell us not to do. There are some sections of the code that are written in terms of ?here is a list of acceptable methods.? In those cases, if something is not on the list, you can conclude that it is not allowed. But most of the code is written in terms of ?this is the minimum required for safety.? It is not a design guide. Powering one sub-panel from another sub-panel is a design choice. The code does not forbid it, so you can do it.

A M.L.O. panel is a sub panel from a main disconnect sub panels can go down stream.Take into account load calcs. compare and make your decision.

My dear friend I could not agree more.

I stood on a ladder all day just because I wouldn?t ask anyone to turn the ladder so I could take a light bulb out. I was too stupid to take the fixture down and turn it. After that I learned that just by asking I could have just turned the bulb. :D

The moral of that story is if you don?t know ask or leave changing light bulbs to those who know what they are doing.
