A: This value is the available short circuit current in amps from the LADWP serving transformer in the event of a ground fault at the service equipment. For single family residential services, mobile homes, or duplexes, this value is guaranteed at 10,000 amps for 200 amp services and 22,000 amps for 320 amp services. For all other services, this value must be calculated by either an Electric Service Representative (ESR) for small services or a Service Planning Engineer for large services.
For more information, go to either Small Service Installations or Large Service Installations.
When the fault current has been calculated, the value will be displayed online when a customer enters a job address, Work Request number, or Project ID number in Service Planning’s online tracking system at Track Electrical Service Installation Status.
