Questions and answers
Why **** I getting a transfer switch fault
GE 20kw Home Generator
A transfer switch fault on your GE 20 kW Home generator may occur due to several reasons:
1. Incorrect Wiring – Ensure that the generator is connected to the transfer switch with the specified wiring. Verify that the #18 AWG twisted pair wiring from the generator control panel to the transfer switch is installed in a separate conduit from high voltage wires unless all wiring is rated for 600V.
2. Improper Neutral or Grounding – The generator’s neutral should be connected to the automatic transfer switch, and the generator must be properly grounded as per NFPA 70, NEC guidelines.
3. Dipswitch Settings – The dipswitches in the transfer switch must be set to match the wattage of the generator. Refer to the Transfer Switch Operator/Installation Manual for proper settings.
4. Utility Voltage Issues – If the utility source voltage drops below 70% of the nominal supply voltage, the transfer switch may detect a fault.
5. Exercise Timer Operation – If the generator is in an exercise cycle, electrical load transfer does not occur. Ensure the transfer switch is operating outside of the exercise cycle.
Check these factors to diagnose and resolve the transfer switch fault.
