Home EV charging draws a sustained load for hours at a time. A Level 2 unit covers daily charging, and the supporting circuit and panel capacity shape what can be added later.
Can two electric vehicles share one circuit?
An Electric Vehicle Energy Management System can divide one circuit between two charging stations, subject to the equipment listings and the calculated load.
100-amp service enough for EV charging?
In many homes it supports one charging station with load management. The capacity left for a heat pump depends on the calculated load.
Canadian Wire Wizards is a licensed electrical contracting company serving the GTA, established in 2018, owned and operated by Demetrois Alafogiannis, with more than 35 years of combined industry experience.
Charging is rarely the only load a household adds. Heat pumps, induction ranges, and electric water heaters draw on the same service. We calculate the total load under the Ontario Electrical Safety Code and provide that calculation in writing.
Provisions for a second vehicle are simplest to install while walls or trenches are open. Oversized conduit, a spare 240 volt circuit position, and equipment that supports load sharing reduce the work involved later. The suitable arrangement depends on the panel location and the route to parking.
Many older homes in Ontario are supplied by service equipment rated at approximately 100 amps. Suitability depends on the calculated load, the existing installation, and the scope of the new work. We assess service size, free breaker positions, panel condition, and grounding and bonding. The things to check before installing an EV charger are worth reviewing early.
Charging work can be combined with planned projects such as panel upgrades, garage renovations, or solar and battery systems. Solar and wind systems connect through inverters, with optional battery storage. They do not increase electrical load demand or panel ampacity requirements, and they do not create bottlenecks in the electrical grid. Efficiency measures such as lighting upgrades leave more of the existing capacity available. Our home EV charger installation work can be scheduled alongside these projects.
Electric vehicle charging is one of the few large loads that can be shifted to off peak hours where the utility rate structure supports it. Connected equipment commonly offers scheduled sessions, consumption data, load sharing, and fault alerts, though features vary by model.
A review a few times a year can cover the cable, the connector pins for discolouration, and the enclosure seals. Extension cords and power bars are not suitable for equipment intended for a dedicated circuit. Repeated breaker tripping or a warm receptacle can indicate a loose connection and warrants examination by a licensed electrician. Safe charging also depends on how the home electrical system supports it.
A new charging circuit is generally permitted and inspected through the Electrical Safety Authority at installation, according to the scope of the work. A further review suits a service upgrade, a second charging station, or a new heat pump. Flickering lights, warm panels, or buzzing breakers warrant prompt attention.
An EV ready home is defined by more than its charging equipment. Service capacity suited to the planned loads, spare breaker positions, oversized conduit, and documented load calculations all contribute, and the right mix depends on the existing installation.
We assess the service and panel, prepare the load calculation, arrange permits and inspections where they apply, and set out the scope in writing. The same approach applies to electric car charger installation for homes and businesses across Toronto and the GTA.
Yes, with a weather rated enclosure and appropriate sealing. Mounting height and cable management matter more outdoors than in a garage.
Level 1 charging works from a standard outlet at a much slower rate. Extension cords and power bars are not suitable.
Usually yes. It often calls for a trenched feeder and sometimes a subpanel, depending on the distance.
That depends on the local utility rate structure and the charging schedule. We can review the options on the selected equipment.
