I would seriously look into using surface wiring (Wiremold) to do this.Hi,
I'm wiring a basement room that has only 1 1/2" from a concrete foundation wall to the finished surface. I believe it is 3/4 furring and 3/4" plaster. I would like to place 15 amp receptacles in these walls but there will not be enough space for even the shallowest boxes. Can I cut out the location for the boxes and then add a 1" thick spacer block to the finished wall with the same size cut out as the electrical box requires to allow for the depth? Then wire as usual?
