Clark Electricians provides generator electrical repair and maintenance services for residential and commercial customers throughout Mount Prospect, IL. Our licensed electricians handle the electrical components of generator systems including transfer switches, output breakers, load connections, control system wiring, and automatic start circuits. We test every generator under load before completing any service.
Generator Electrical Components We Service
Generator repair work covers a range of electrical components and systems. Automatic transfer switches are among the most critical and most service-prone components in a standby generator system. The transfer switch is responsible for detecting utility power loss, signaling the generator to start, and switching your home or business circuits from utility to generator power. Transfer switch failures cause generators to either fail to start or fail to connect to the load.
Automatic Transfer Switches and Load Management
Transfer switch service includes inspecting and cleaning contacts, verifying switching speed and timing, testing automatic start signaling, and checking load connection integrity. We also assess whether the transfer switch is correctly matched to the generator capacity and connected load, as mismatched sizing is a common source of transfer switch failures. For commercial standby systems, we verify that the transfer switch meets code requirements for the building occupancy.
Testing a generator under actual load conditions annually is critical. Many generators that appear to start and run normally at no load fail or shut down when asked to carry the circuits they are intended to power. Clark Electricians performs load testing as part of every generator service in Mount Prospect, IL to ensure your generator will actually power your home or business during an outage.
