Finishing Basement--use plastic sheathed cable or conduit?
We are finishing the basement in our 2 year old house right now. We will be adding 4 circuits and approximately 40 new outlets/switches/junction boxes. I see that plastic sheathed cable is the typical choice for pulling new wire. However, when I checked the upstairs outlets, I see the builder used metal conduit with 2 wires, no ground wire. Any reason for this? Our home is an upscale home in a custom executive neighborhood, so far we have found no corners cut by the builder, so I don't want to cut corners ourselves if there's a valid reason to choose metal conduit over sheathed cable. Any advice?
