Frequently Asked Questions About Panel Upgrades

Clear details about 100A to 200A service overhauls, Cambridge Hydro disconnections, and ESA safety permits.

How long will my home be without power during a panel upgrade?
During a standard 100A to 200A panel upgrade in Cambridge, power is temporarily disconnected by Cambridge Hydro while our master electricians replace the service mast, meter base, and breaker panel. The entire power interruption typically lasts between 4 to 6 hours, and power is fully restored the same day once the installation passes initial safety checks.
Do you handle Cambridge Hydro coordination and ESA permits?
Yes, we take care of the entire administrative process from start to finish. We coordinate the disconnection and reconnection schedules directly with Cambridge Hydro and file all necessary Electrical Safety Authority (ESA) permits so your panel upgrade complies 100% with provincial regulations.
Why do insurance companies require older homes to get an electrical panel upgrade?
Many vintage properties in Cambridge still operate on outdated 60A or 100A fuse boxes or obsolete breaker brands that pose thermal overload and fire risks. Insurance providers frequently request a professional electrical panel upgrade to modern 200A copper standards before issuing or renewing home insurance policies.
What should I do if I need an emergency panel upgrade near me?
If you notice sparking, burning plastic smells, hot breaker switches, or complete power loss originating from your breaker box, you need an urgent response. If you are searching for an emergency panel upgrade near me in Cambridge, call our local dispatch team immediately so we can isolate the hazard and schedule priority replacement.
