Electrical Preventive Maintenance Checklist: Residential

Here’s a list of pointers:

• Check cable assemblies and other wiring methods in rooms, hallways, stairways, and attics.

• Check cable installations and circuit boxes for general suitability.

• Examine boxes for warning lights and other irregularities.

• Ensure equipment grounding conductors are suitable for use according to the size and quantity of equipment.

• Examine lighting outlets and ensure they are properly wider on general lighting circuits.

• Survey relevant receptacle outlets for branch circuit type (ensure they’re supplied by small appliance circuits).

• Identify and repair frayed wires close to water outlets in bathrooms.

• Look for irregular wiring arrangements and lighting outlets on walls.

• Check the grounding electrode conductor connections and buried connections for heat damage or suitable placement.

• Examine and repair electrical surge protection units (where installed).

• Inspect timers, power supply units, relays, and control wiring for humidity or temperature damage, as well as regular wear.

• Detect signs of electrical disturbance as an indicator of minor shorts and sparking.

• Ensure proper voltage in all rooms and areas of majority electrical usage.
