Feeder Sizing

Design Master Electrical RT is an add-in for Revit that sizes panel feeders.


Feeders are sized automatically based upon the rating of the overcurrent protection for the electrical equipment. You can control the default feeder size based upon the ampacity of the wire.

Individual feeders can be customized as needed. Upsize a wire based upon voltage drop or choose to use aluminum for a specific feeder to cut costs.

A schedule of all the feeder sizes can be created and viewed in Revit. It lists each piece of electrical equipment in the project and the corresponding feeder size. The electrical equipment is grouped by the ampacity of the upstream OCP.

“I can’t imagine designing in Revit without Electrical RT.”
