North American home service panel single line diagram

This residential electrical single line diagram shows a North American 120/240 V home service panel. The utility service enters a 200 A meter socket and main service disconnect before reaching the main panel. The panel supplies 240 V range and dryer circuits alongside 120 V kitchen, bedroom, and garage circuits.

What is in this drawing

Read the decisions behind it.

01200 A service

Meter socket and service disconnect establish the dwelling’s main rating.

02Two-pole appliances

The range and dryer use 240 V branch breakers.

03GFCI locations

Kitchen and garage receptacles have ground-fault protection.

04AFCI branch

Bedroom lighting is shown on an arc-fault-protected circuit.

05Conductor labels

Branch conductor sizes are visible at each load.

Use this for a conventional detached home under North American practice. Local code determines the final AFCI, GFCI, service, and conductor requirements.

FAQ

Common questions

Why are range and dryer breakers two-pole?

They supply 240 V loads from both service legs and disconnect both ungrounded conductors together.

What is the difference between GFCI and AFCI?

GFCI protection responds to ground-fault current, while AFCI protection detects hazardous arcing patterns.

Is this a permit-ready panel schedule?

No. It is a single line; a permit set normally also needs load calculations and a detailed panel schedule.
