What is the distance allowed between where the service wires enter your home and the breaker box?

  • This site says that there's no limit specified in the NEC, but there may be a limit imposed by your local jurisdiction. Since I can't vouch for this source (or the current applicability of an article published 6 years ago), I'll let someone with access to the NEC to post an more definitive answer.

  • Isn't it <5% for the drop?

  • Moot the problem by getting a meter pan with a main breaker in it. Kris he's asking about length not voltage drop, there are other factors too, notably physical protection. May 20, 2017 at 13:28

The NEC simply says as close as practical. Some locations do impose an actual distance number. Most areas have a limit of 5-6 feet into the structure to the main panel/disconnect.

Your local authority/inspector will be the only one who can tell you for sure.

  • Thanks. Owing the the layout of my utility room, I'm pretty sure it's going to be about 7-8' to where I can locate the panel to have the required working space in front of it. Aug 2, 2015 at 17:00
