Was there ever a point in time that splices were not allowed inside of a panel enclosure? There seem to be alot of people that think this is not permitted. I just wonder why.
 
Re: Smal issue.... just curious

I've replaced panels from as early as the late 50's that had late 50's inspection stickers and vintage soldered and taped splices inside them. I assume that it was okay then. I'm sure someone here knows.

I often thought that collecting old NEC's would be a neat thing to do, but I've only managed to find just a couple.

Here is what the 1965 NEC says:

"373-8. Switch Enclosures. Switch enclosures shall not be used as junction boxes, auxiliary gutters or raceways for conductors feeding through or tappng off to other switches, unless designs suitable for the purpose are employed to provide adequate space for this purpose."

110-15 of the '65 version has the same wording as today's version for splicing.

It sounds very much like todays rule.

I agree Scott. I wonder why people think that too. It seems almost natural though to expect there's something wrong with it.

It's not uncommon for me to explain to people that putting two wires under a breaker terminal might actually be the incorrect method instead.

My question is this: If you're doing a service change out and upgrade the panel to larger size, some of those conductors might be too short to land accordingly. So why could'nt you splice onto them within the panel. It would look better than adding j-boxes about the panel to make these splices in.
 
Re: Smal issue.... just curious

Getting started, that is my point. You are allowed to splice in the panel. I wonder why many think you are not.
 
Re: Smal issue.... just curious

It is hard to know how these things get started, may be because it is not a j-box therefore no splices?

In my area of Massachusetts there were many inspectors who thought you could only have two receptacle outlets on the required small appliance branch circuits. I was once told to run eight circuits to the counter top outlets , 2 to the dinning room and one for the frige, why ? Who knows?

At last nights contractor meeting, we had a rep from a transfer switch company, and she corrected a contractor who blurted out that her product was no good, as it required splicing in a panel, and that was not allowed. You should have seen the many shades of red he turned when she replied with the proper section number and told him that it is permitted - lots of laughter from the guys.
