“Draw a North American residential electrical single line diagram with a 120/240 V utility service, 200 A meter and main disconnect, service panel, electric range, dryer, kitchen GFCI receptacles, bedroom AFCI lighting, and garage GFCI receptacles.”
Comprenez les décisions qui le sous-tendent.
Meter socket and service disconnect establish the dwelling’s main rating.
The range and dryer use 240 V branch breakers.
Kitchen and garage receptacles have ground-fault protection.
Bedroom lighting is shown on an arc-fault-protected circuit.
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.
Questions fréquentes
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.
