We are remodeling our kitchen and getting quotes for updating the electrical. We have received 2 quotes so far.
The service panel is on the exterior of the house opposite the location of the kitchen.
First quote calls for running UF-B through the crawlspace going through the exterior wall inside EMT that enters directly into the breaker box.
Second quote calls for running NM-B through the attic and going through the exterior wall inside EMT that enters directly into the breaker box.
The second quote is less expensive. It looks like the main reason is the cost of the UF-B vs. NM-B. When asked about the difference the first electrician said that the only option with an exterior panel is to use UF-B, because the wire is exiting the controlled envelop of the house and may become wet. The second electrician disagrees and says that NM-B is allowed to exit the envelope of the house if it is going directly into the breaker box and is protected in conduit.
Who is correct? I can see both sides.
We are in NC.
