Electric Service Reqs

Belmont Light’s distribution circuits generally operate with automatic re‐closers, which activate following a trip without regard to whether the Facility is keeping the circuit energized. The Interconnecting Customer is responsible for protecting their equipment from being re‐connected out of synch with Belmont Light's system. For Facilities that utilize photovoltaic (PV) technology: It is required that the system be installed in compliance with IEEE Standard 929‐ 2000, “IEEE Recommended Practice for Utility Interface of (PV) Systems” or the applicable updated standard. The inverter shall meet the Underwriters Laboratories Inc. Standard UL 1741, “Static Inverters and Charge Controllers for Use in PV Power Systems” or the applicable updated standard.

Compiled from public records, 2026. Tariffs and interconnection rules change; verify with Belmont Municipal Light Department before you rely on this. The useful move: if an installer says you need a main panel upgrade, ask how these tap and interconnection policies were considered first.
