Question:
Good Day,
I have to install a feeder for a panelboard in my workshop. There is a 100-ampere service on the building that contains the workshop. Can I use Type SEU cable as the feeder for the new panel?

Answer:
Hi Art,
Feeders are required to include an equipment grounding conductor as indicated in 215.6. The feeder should include an insulated grounded conductor (neutral) and the required equipment grounding conductor. Type SER cable provides both in the same cable assembly. The neutrals and equipment grounding conductors are required to be insulated from each other in the new panelboard supplied by the feeder. See Section 250.24(A)(5) and 250.142(B).
