Weather your system has a manual or an automatic transfer switch, it should be tested regularly to verify the function of the switch. Most Automatic switches have a small battery that needs to be replaced every 5 years or so. Automatic switches also often have exerciser clocks that trigger the unit to run for a given period of time at a regular interval. This is a great feature to ensure your unit is running regularly. Engines that sit without running for long periods of time are prone to problems.
Our service includes a complete inspection and testing of your transfer switch, verification of the exerciser clock, and thorough checking of all wire connections. We can also reset the exerciser clock on most switches to operate at a time that’s convenient for you. Service-rated transfer switch testing is included with our Annual Generator Service or can be scheduled separately.
As a best practice we would also recommend that you include our Power Failure Simulation Test to ensure that all aspects of the system are functioning together. Call us today at (503)357-3839 for more information!
What’s Included in a Transfer Switch Test?
A thorough transfer switch test ensures your backup power system operates safely and reliably when you need it most. During the inspection, our technicians:
- Check and tighten buswork, contacts, and hardware for signs of wear, corrosion, or loose connections.
- Inspect control wiring, power cables, and cabinet interiors for deterioration or unusual conditions.
- Evaluate mechanical components, including stationary and movable contacts, for proper function.
- Test system indicators like pilot lamps and exercise clocks to confirm accurate operation.
- Remove dust and moisture, maintain lubrication, and replace control module batteries as needed.
- Perform a power transfer test (if applicable) to confirm the switch safely transfers load between primary and backup power.
By performing these steps, a transfer switch test helps prevent unexpected failures, extends the lifespan of your equipment, and ensures your home or business stays powered during outages.
