Generator Transfer Switch Testing – Protect Your Backup Power
Regular generator transfer switch testing is essential to ensure your backup power system functions flawlessly during an outage. Whether your system uses a manual transfer switch or an automatic transfer switch, testing is crucial for reliability. Without regular testing, you risk failing to switch to backup power when you need it most.
Why You Need Transfer Switch Testing:
✅ Avoid power failure risks: Ensure the switch functions correctly and can transfer power smoothly during an outage.
✅ Extend the lifespan of your generator: Regular testing and maintenance help prevent system failure and unnecessary repairs.
✅ Prevent costly repairs: Avoid unexpected issues by verifying the switch and components are in top condition.
✅ Peace of mind: Know that your generator transfer switch is ready to provide reliable backup power when needed.
What We Test and Inspect:
- Transfer switch function: Ensure proper operation of both manual and automatic transfer switches.
- Exerciser clocks: Test the clock settings to ensure it’s running at the correct interval for reliable operation.
- Battery replacement: Verify and replace small batteries in automatic transfer switches as needed (typically every 5 years).
- Wire connections: Inspect all connections for safety and reliability.
- Convenient scheduling: We’ll reset exerciser clocks to times that work best for you.
Optional Power Failure Simulation Test:
We recommend adding our Power Failure Simulation Test to ensure all components of your backup power system are working in sync.
