Over-Current Protection For Subpanels

A main breaker is not required for a subpanel if over-current protection is provided for the feeder conductors.

If the subpanel’s feeder cables are not connected to breakers in the service panel, where would they be coming from?

How would the SEC for subpanel be wired in the service panel?

Using what’s referred to as a feed-through lugs.

Simon, I haven’t been exposed to feed-through lugs, but the concept makes sense.

Thanks for the info!

You will see it eventually.

Sometimes its just from a Service disconnect breaker.
