Electrical – Expanding two gang box to three gang with metal conduit

conduitelectrical

I live in Chicago so everything in my walls is in metal conduit. In what is currently a two gang box, all three of the top punch out holes are connected to metal conduit. I'd like to expand this to a three gang box, but then the top punch outs will no longer line up with the metal conduits that feed it.

Is there a simple way I can alter the positions of the conduits so they would line up with a three gang box?

The conduits will bend even if rigid, if thin wall or emt they are easily bent into place.

I pull my wiring out and mark with a paint pen or sharpie stripes take a picture or draw a schematic black wire 1 has 1 stripe white wire 1 has 1. Red 1 has 1 then black 2 has 2 etc. normally not more than 5 in a box keeps from having so many stripes).

Power off of corse. Disconnect switches, pull nuts, remove fasteners(screws or nails) fit wires and conduit into new box install locknuts /bushings if needed. Anchor usually with screws install switches.

A small pry bar or wonder bar can be a lifesaver muscling the conduit.

try to not skin the wires if you do skin them the world is not over some shrink tubing will fix a skinned bit of insulation.

I have done jobs with rigid a foot up in the wall it was anchored but I could get the conduit into the box with a bit of brute force.
