What service entrance means
The service entrance is the wiring and equipment that bring utility power into the house, from the service drop or lateral through the meter to the main disconnect.
Also called service entrance conductors, SE cable.
Where it matters on a electrical job
Service upgrades mean coordinating a utility disconnect and reconnect, often the longest wait on the job. Put that step on the schedule and tell the customer when the power will be off.
What the model code says
- The service disconnect must be at a readily accessible place outside or inside nearest where the service conductors enter, and never in a bathroom. (IRC 2021, Chapter 36)
- For a 100 through 400 amp dwelling service, service conductors may be sized at 83 percent of the service rating. (IRC 2021, Chapter 36)
