Rigid Aluminum Conduit (RAC)

Rigid Aluminum Conduit (RAC)

Rigid Aluminum Conduit (RAC)

(OP)
Using RAC for a few single phase 120v branch circuits. Concerned about the non-ferrous properties of aluminum and ability to shield emi from branch circuit conductors with conduit that will be light fixtures from a dimming control panel. There is some audio equipment about 15' away from where the conduit is installed.

Anyone have experience with using aluminum rigid conduit and emi problems?

Thanks.

RE: Rigid Aluminum Conduit (RAC)

Rigid Aluminum Conduit is not as good as Rigid Steel Conduit [according some studies aluminum is about 5% from steel EMI reducing effect].But 15' is a good clearance for lighting wire-usually 2-5 A, I think. See:
