Hi, I am currently finishing my basement and decided to move a baseboard heater from one wall to an other 10 feet away.
I would rather not have to run a completely new wire to the new destination.
What I was wondering is could I just splice the wires from the baseboard heater and run it to the new location and re-install the heater there? (basically increasing the length of the wires).
I was told I would need to splice those wires in a junction box.
The problem with that is that it can not be covered by drywall or anything else.
Could I use an outlet box as a junction box instead?
That way at least the wall would look like an outlet and not a metal square.
Is that legal?
Thanks

Isn't your outlet 120 and the heater 240?

Yes but it will have to power to it, it will be an empty outlet, was hoping to use that as a junction box instead.

You can do this if the box you are using has enough capacity. By this I mean wire fill.
You need to know the size of the box and the number of conductors within.

So would a standard wall plug cut it?
Like this one for example. http://www.homedepot.ca/product/device-box-single-gang-125-in-cu-welded/914369

so would a standard wall plug cut it?Do you mean the box?
Maybe, but probably not. No way to tell without the details.
