Generator Changeovers

Automatic and manual generator changeover systems for seamless backup power during outages, installed to safety standards.

Service Overview

Reliable automatic and manual generator changeover systems for homes, businesses and industrial facilities. We supply and install changeover switches that seamlessly transfer power during outages, protecting your equipment and ensuring uninterrupted operations. Our systems are designed for safety, compliance and peace of mind.

A changeover switch is the piece of equipment that lets a generator feed your building safely, and it's not optional. Connecting a generator without one means back-feeding into the municipal supply — which can kill a City Power technician working on the line and will certainly damage your generator when the power comes back. Every changeover system we install has proper mechanical or electrical interlocking, and we won't connect a generator without it.

The first question on any generator job is manual or automatic. A manual changeover is simpler and cheaper — you walk out, start the generator, and throw the switch. An automatic system senses the outage, starts the generator, and transfers the load on its own, which matters for businesses that can't have someone on site at 2am. We'll work through your needs and your budget and recommend honestly, because an auto changeover on a house that only needs the lights and the alarm is money wasted.

Sizing matters as much as the switch. If the generator is too small for the load, it hunts and stalls under load; if it's oversized, it runs inefficiently and costs more to fuel. We check the loads you actually want to run during an outage — not everything in the building — and balance them across phases on three-phase installations. The system is tested, certified and issued with a COC, and we maintain generator installations on contract for clients who can't afford a failed start when the grid drops.
