Is a service loop required on install of a TVSS SurgeArrest Panel Mount device?

Published date: 23 March 2020


The Panel Mount SurgeArrest is hardwired so there is the question of whether or not a service loop is required by the NEC. According to the National Electric Code, Article 300 section 14.

Product Line:

All TVSS Panel Mount Devices


All TVSS Panel Mount Devices

Cause / Resolution:

Length of Free Conductors at Outlets, Junctions, and Switch Points. At least 6 in. (152 mm) of free conductor shall be left at each outlet, junction, and switch point for splices or the connection of fixtures or devices.

Exception: Conductors that are not spliced or terminated at the outlet, junction or switch point.""

The Panel Mount Protectors do not fall under these three items, therefore no service loop is required by the NEC for wiring internal to our product. However, when connected to the Circuit Breaker inside the AC Panel, the wires will have to have a 6"" Service loop."
