EV Charger Installation With a 100 Amp Panel

Have a 100 amp electrical service and want to install an EV charger? You may not need to upgrade to 200 amps.

JAC Electric helps homeowners in Mississauga and the GTA determine whether their existing 100 amp service can support home EV charging, whether load management may be appropriate, or whether a service upgrade actually makes sense.

100 AMP SERVICE + EV CHARGING

Can You Install an EV Charger With a 100 Amp Service?

Yes, potentially. A 100 amp service does not automatically mean you need a 200 amp upgrade to install an EV charger. The right solution depends on your home's existing electrical demand and the charger you want to install.

01

Existing Capacity

Your 100 amp service may already have enough available capacity for the EV charging setup you need.

02

Load Management

If capacity is limited, EV load management may allow charging without automatically upgrading the entire service.

03

200 Amp Upgrade

If the home needs additional electrical capacity, a 200 amp service upgrade may be the better long-term solution.

HOW WE CHECK YOUR HOME

Is Your 100 Amp Service Ready?

WHEN CAPACITY IS LIMITED

Load Management Can Be Another Option.

If your 100 amp service does not have enough available capacity for the EV charger you want, that does not automatically mean the entire electrical service needs to be upgraded.

An EV load management system can manage charging around the electrical demand already being used by the home.

COMMON QUESTIONS

100 Amp Panel + EV Charger Frequently Asked Questions

Common questions from Mississauga homeowners who want to add an EV charger to a home with a 100 amp electrical service.

Can I install an EV charger with a 100 amp panel? +
Potentially, yes. Having a 100 amp electrical service does not automatically mean you need to upgrade to 200 amps. The home's existing electrical demand and the requirements of the EV charger should be assessed first.
Do I need a 200 amp service for an EV charger? +
Not necessarily. Some homes may have enough available capacity, while others may be candidates for EV load management. A service upgrade may make sense when additional electrical capacity is actually required.
What if my 100 amp service doesn't have enough capacity? +
Load management may be an option. It can manage EV charging around the electrical demand of the home rather than automatically increasing the size of the electrical service. Learn more about EV load management →
Can I install a Level 2 charger on a 100 amp service? +
It may be possible depending on the home's electrical demand, available capacity and the charging setup being installed. Learn about Level 2 EV charger installation →
Can a Tesla charger be installed with a 100 amp panel? +
Potentially. The electrical service, existing household loads and planned Tesla charging setup should be reviewed before determining the appropriate installation. View Tesla charger installation →
