What is code for relocating an electrical panel?
Friday, November 12, 2021
When moving an electrical panel box, there are four areas listed by National Electrical Code (NEC) at 240.42(C,D,E,F) where a panel cannot be located:
1) Where exposed to physical damage.
2) In the vicinity of easily ignitable material. Clothes closets are specifically noted as an area with easily ignitable material (hanging clothes).
3) In bathrooms.
4) Over steps.
Plus, there are also four other location considerations:
a) The panel must have a clear working space in front of it that is 2.5 feet (30”) wide, 3 feet (36”) deep, and 6.5 feet (78”) high [NEC 110.26 (A)(1&2)].
b) The 2.5 foot width in front of the panel does not have to be centered.
c) Storage is not allowed in the required working space, per NEC 110.26(B)
d) The panel door must swing open a minimum of 90º, per NEC 110.26(A)(2).
And there might even be one more. If your local building department has adopted the 2020 NEC for their inspections, then you will also be required to have a main disconnect box on the outside of your home in a readily accessible location.
