I have an existing 220 line (10-2 wire), that is an outlet for a dust collector.
I need to move the dust collector about 5 more feet down the wall. So the outlet needs to move 5 feet too.
Any problem with taking the plug out of the metal box, using it as a junction box instead, and splicing in another 5 feet of #10 wire to a new outlet down the wall?
I know this is fine with 110 but I don't do much with 220 ever, so just making sure.
