Is a permit needed for the "like-in-kind" replacement of a feeder circuit breaker?

In Washington State, a permit is always required for the replacement of electrical components in a residential or commercial setting, including the replacement of a feeder circuit breaker, even if it is a "like-in-kind" replacement. This regulation is in place to ensure that all electrical work is performed following safety standards and building codes, which protect both the property and its occupants.

When it comes to electrical permits, the requirement applies regardless of the nature of the replacement; simply swapping out one breaker for another of the same type does not exempt the work from permitting. Permitting helps to ensure that any changes or repairs made to the electrical system are inspected and deemed safe by a qualified professional. Additionally, obtaining a permit ensures that the work is documented, which can be important for future property sales or inspections.

The other provided options may suggest varying circumstances where permits might not be necessary, but those do not align with Washington’s electrical code requirements, which mandate consistent oversight for all electrical replacements to maintain safety standards across all installations.
