Many states are now starting to adopt the 2020 version of the National Electrical Code. A few highlights of the changes that apply to houses are:
230.85 Emergency Disconnects. For one and two-family dwellings units, all service conductors shall terminate in a disconnecting means having a short-circuit current rating equal to or greater than the available fault current, installed in a readily accessible outdoor location. If more than one disconnect is provided, they shall be grouped.
230.67 Surge Protection.
(A) Surge-Protective Device. All services supplying dwelling units shall be provided with a surge-protective device (SPD).
(B) Location. The SPD shall be an integral part of the service equipment or shall be located immediately adjacent thereto.
Exception: The SPD shall not be required to be located in the service equipment as required in (B) if located at each next level distribution equipment downstream toward the load.
(C) Type. The SPD shall be a Type 1 or Type 2 SPD.
(D) Replacement. Where service equipment is replaced, all of the requirements of this section shall apply.
Be sure to check your location to determine what version is enforced in your location.
