My home has 10 junction boxes in the ceiling of the basement. The
original electrician moved the panel box (circuit breakers) about 20
feet to the left and then ran short runs to the original wires and
connected them at regular junction boxes.
I want to put 1 large junction box in the wall and make all of the
connections in it.
Can anyone tell me the name of such a junction box and possibly
recommend a source.
If I understand you correctly, you have 10 different circuits in 10
junction boxes that were put there to allow the circuits to reach the
new panel box installation. You want to put all 10 of those circuits
into a single large junction box.
I seem to recall that you are not allowed to have mulitple circuits
share the same junction box. Can anyone confirm or deny that?
You might be able to move these *boxes* into a single cabinet. (must
have easy maintenance access to them though.) The trick is getting
all the wires long enough. ;)
It's funny... I was just asking about doing something similar to that
setup in another thread. I wanted to put a switch and receptacle on
each of the circuits so that I could switch the circuit without
switching the breaker.
Ich habe keine Ahnung was das bedeutet, oder vielleicht doch?
Why bother? you can buy them most any where, at least any electrical supply
will have them, and one hell of a lot cheaper than a sheet metal shop would
Plus the box should be UL listed, one made by a tin bender will probably
make your insurance company nervous!
Pretty sure the electrical inspector would in fact make a person tear it out
and use a listed enclosure instead.
Although the last time I got into that can of worms we did get by with
listed enclosure and a fabricated lid--a bit of a loophole that the
inspector apparently noted and then let slide was his book said "listed
enclosure with metal cover" or something to that effect......
If the OP has time to hunt for a bargain then suggest he might consider
I'd bet a lot of those circuits could have their final homeruns completely
replaced, eliminating the need for most of the splices. Do any of those cables
go for only a short distance before the 1st device on the circuit, like a
basement light, or the furnace, a basement outlet?
As for the ones that disappear up to the 1st floor, a few might only feed an
outlet directly above and they too can be easily replaced.
You may find you really only need a couple of regular 1900 boxes.
Go to an electrical supply house. Ask for a splice box or pull box. They
will have an assortment of sizes such as 10" x 10" x 4" or 12" x 12" x 6",
etc. Get one with knockouts in it already. What you need to do is figure
out the number of conductors that will ultimately be in the box. Check the
code book for the cubic inch requirements for the size conductors that you
have. I think #12 requires 2.25 cubic inches per conductor, but I could be
wrong as I don't have my book handy. Get a box that is a little bigger than
what is required.
You made need a hole saw or knockout punch to make additional holes in the
junction box. A 7/8" unibit will work also for half inch trade size.
