Is Your Panel Telling You
Something?
An aging or undersized panel is a fire and safety hazard. If you're experiencing any of the following, contact Tilco today.
Breakers Trip Frequently
Constantly resetting tripped breakers means your panel can't handle the electrical load. This is a fire risk, not a minor inconvenience.
Flickering or Dimming Lights
Lights that dim when appliances run signal that circuits are overloaded. Your panel is struggling to distribute power properly.
Fuse Box Still in Use
Older fuse panels are no longer code-compliant and may void your home insurance. A modern breaker panel is safer and insurer-approved.
Not Enough Circuits
Running multiple extension cords or power bars everywhere is a sign your panel doesn't have enough capacity for today's electrical demands.
Burning Smell or Scorch Marks
Any burning odour or discolouration around your panel is an emergency. Turn off the main breaker and call Tilco immediately.
Home Renovation or Addition
Adding a new room, EV charger, hot tub, or major appliance often requires a panel upgrade to handle the additional load safely.
Recognise any of these? Don't wait. Panel issues get more dangerous over time.
