Commercial Electrical Maintenance Checklist for Business Owners

By the Broad Moor Electric team · 2026-09-27

Electrical failures rarely announce themselves. A simple maintenance program from a commercial electrician prevents most of the outages, fire risks and inspection findings that cost businesses money.

Annually

• Thermal imaging scan of panels and disconnects to find hot connections.
• Torque check on main lugs and breakers.
• Emergency and exit lighting battery test.
• GFCI test in kitchens, restrooms and exterior.
• Surge protection device status check — see surge protection.

Every two to three years

• Lighting audit — most buildings still have fluorescent fixtures that an led lighting retrofit would pay back within two years.
• Load study if you have added equipment.
• Parking lot lighting and pole inspection.

Immediately

• Any warm, buzzing or discolored breaker.
• Repeated tripping on a circuit.
• Flickering that coincides with equipment starting.
