Calvin Burton of Fox Electric, Ltd., Arlington, Texas, sent in this photo of a unique electrical service his safety manager recently ran across. As Burton notes, this installation “gives a new meaning to service door.”

The rules for the placement and installation of service equipment — disconnecting means can be found in 230.70. The requirement states, ”Means shall be provided to disconnect all conductors in a building or other structure from the service entrance conductors.
”(A) Location. The service disconnecting means shall be installed in accordance with 230.70(A)(1), (A)(2), and (A)(3).

- ”(2) Bathrooms. Service disconnecting means shall not be installed in bathrooms.
- ”(3) Remote Control. Where a remote control device(s) is used to actuate the service disconnecting means, the service disconnecting means shall be located in accordance with 230.70(A)(1).
