EV Charger Installation in Cambridge
A Level 2 charger is one of the largest loads a Cambridge house will ever add, and in a century home the panel was never meant to see it. The charger is the easy purchase; the circuit and the capacity behind it are the job.
Cambridge's EV requests come from both ends of its housing. The subdivisions built since the 2000s in the north and east ends — off Franklin, Saginaw, Townline and in the growing streets around Hespeler Road — have 200-amp services, breaker panels in the basement and attached garages, and the question is which wall. The three old cores and the post-war rings around them have smaller services, panels that may be full, and cars on driveways or at the kerb, and the question is whether the house can feed a charger without a larger service. The contractor answers that before anyone orders a charger.
Capacity is a calculation
Most Level 2 chargers want a dedicated 40- or 50-amp circuit, which puts them in the same league as the range and the dryer combined. Whether a service can take that is settled by a load calculation under the Ontario Electrical Safety Code, which the contractor performs and shows you. A 200-amp north-end house passes easily. A 100-amp Preston Heights side-split may pass, may need a load-management device that pauses charging when the rest of the house is drawing hard, or may need a bigger service. A fused Galt stone house does not pass, and the service upgrade comes first.
Beyond capacity
The contractor also needs two free slots in the panel for a two-pole breaker, or a subpanel if the panel is full. The route matters: a panel beneath the garage is a short job, while a panel at the back of a century home with parking at the kerb means conduit along the foundation or a penetration through stone where the wall permits. You choose between a hardwired unit, which is the tidier installation, and a plug-in unit on a properly rated and protected receptacle, which can move house with you. Outdoor installations need a weather-rated unit, a proper outdoor box and a position that keeps the cable off the path. Any Level 2 charger sold in Canada uses the standard connector; the contractor installs the one you have bought or recommends one sized to the circuit, and nothing on this site is sold or sponsored.
The utility step
GrandBridge Energy's service request page lists installing an EV charger among the examples of work for which a service layout is required when booking with the utility. Where a charger installation changes the service or the metering, the contractor submits that layout and books whatever appointment is needed; where it is simply a new circuit on an adequate existing service, it is an ESA matter and the utility is not involved. You are told which applies on the quote.
Century homes, driveways and rural properties
A charger for a Galt, Preston or Hespeler century home usually goes outdoors, since there is rarely an attached garage, and it usually raises the service question, since the panel is small and already busy. Where knob-and-tube or aluminum is present the charger circuit is new copper from the panel and is unaffected, but the panel work needed to feed it brings the old wiring into the plan. On the North Dumfries properties the charger often goes in a detached shop or garage on its own feeder, and it is designed alongside the feeder and subpanel rather than squeezed onto a feed that was marginal already.
Inspection, and rebates
A new charger circuit needs a notification filed with the Electrical Safety Authority and a review of the finished work; the contractor files it and the Certificate of Acceptance follows. On incentives: we could not verify any current Ontario provincial rebate for a home charger as of autumn 2026, and this site does not promise one. Programs change at every level of government and at utilities, so confirm with GrandBridge Energy and the province at the time you book rather than relying on a figure from any website.
Frequently asked questions
Can my panel handle a Level 2 charger?
The load calculation answers that and is part of the quote. A 200-amp service in a newer house almost always can. A 100-amp service depends on the other electric loads, and load management or a subpanel often solves it. A fuse service cannot and needs upgrading first.
Does GrandBridge Energy need to be involved?
Only if the installation changes the service or the metering. GrandBridge lists EV charger installation among the work that needs a service layout when booking with them, and the contractor handles that where it applies. A new circuit on an adequate existing service is an ESA matter only.
Is there a rebate for a home charger in Cambridge?
We could not verify any current Ontario provincial rebate for home chargers and will not quote one. Check with GrandBridge Energy and the province when you book. Any program that does exist generally requires a licensed installation with ESA paperwork, which this work includes.
