National Electrical Installation Standards

Standards as High as Your Own

Monday, August 29, 2022


Greetings CQD, my house was built in 1962. The service panel was in the garage where the electric drop was located. In the early '70s, the garage was converted to a bedroom, with the service panel then located in a "powder room". I purchased this house in 2019, with the above conditions. Do I have to have the service panel moved? I want to add PV Solar to my house. In Tennessee, EMT is not used and all wiring is NM Cable. I think this would be an over $15K project to relocate the service panel. Any suggestions?

Hello Kenneth, thank you for your question. We do not comment on the cost of a project or repair, however, we can provide some guidance on the code questions. In general, the National Electrical Code (NEC) applies to new installations and is only applied retroactively if a code section specifically requires a retroactive application. Under the current 2020 edition of the NEC, Section 240.24(E) prohibits overcurrent protection devices like branch circuit breakers, from being installed in the bathroom of a dwelling unit. It is always advisable to check with the local AHJ as many jurisdictions have specific rules that apply to existing electrical installations.
