For a business, an electrical failure is not just an inconvenience, it is closed doors and lost revenue. A simple preventive maintenance routine catches most problems before they take down your operation. Here is a checklist Denver Metro facilities can work from.
Quarterly
- Check the panel and breakers for heat, discoloration, or a burning smell.
- Test GFCI and AFCI protection in kitchens, restrooms, and wet areas.
- Inspect exit signs and emergency egress lighting and test the battery backup.
- Walk the space for damaged cords, overloaded outlets, and improvised power strips.
Annually
- Thermal-image the main panel and major disconnects to find loose or overheating connections.
- Tighten and torque-check electrical connections per manufacturer spec.
- Test the transfer switch and any standby generator under load.
- Review the load on each panel against capacity, especially if you have added equipment.
- Verify labeling and update the panel directory after any changes.
Before you add equipment
New kitchen equipment, EV chargers for a fleet, server racks, or a tenant build-out can quietly push a panel past its safe capacity. A quick load calculation before you buy prevents nuisance trips and code problems later.
Why a contract makes sense
A preventive maintenance agreement puts these checks on a schedule, gives you priority response when something does go wrong, and creates the documentation your insurer and owners want to see. See our commercial electrical service or talk to us about a maintenance plan at (303) 699-1417.
