Should I hardwire or plug in my NB EV charger?

For most New Brunswick homeowners, a hardwired Level 2 EV charger is the better choice — it's safer, more reliable, and often required by the charger manufacturer for warranty purposes.

Here's the practical breakdown of both options:

Hardwired chargers are permanently connected to a dedicated circuit, typically 40A (to deliver 32A of continuous charging). There's no plug to loosen over time, no heat buildup at a connection point, and no risk of someone accidentally unplugging it. Most premium chargers — Tesla Wall Connector, ChargePoint Home Flex, Wallbox — are designed primarily for hardwired installation. This is the setup most NB electricians will recommend.

Plug-in (NEMA 14-50) chargers connect to a 240V/50A outlet, similar to what your electric range uses. The advantage is portability — you can take the charger with you if you move. Some homeowners prefer this flexibility, and it's a legitimate option. However, the outlet and plug connection point experiences repeated heat cycling every time you charge, which over years can degrade the connection. A loose or degraded NEMA 14-50 connection is a real fire risk, especially in a garage environment.

NB-Specific Considerations

New Brunswick's climate plays a role here. Cold Maritime winters mean your car will draw maximum amperage regularly (cold batteries charge harder), putting consistent thermal stress on any plug connection. A hardwired connection eliminates that variable entirely. If your garage is unheated — common in NB — that temperature cycling is even more pronounced.

From a TSANB permit standpoint, both options require a permit and licensed electrician. You'll need a dedicated circuit either way — a 40A breaker with 8 AWG wire for a NEMA 14-50 outlet, or the same circuit run directly to the charger. The permit and inspection process is identical regardless of which you choose.

Cost difference is minimal. A hardwired installation typically runs $1,200 – $1,800 in the NB market (assuming your panel has capacity). A NEMA 14-50 outlet installation is slightly less — roughly $900 – $1,400 — but you'll still need to purchase a portable EVSE separately, which often closes that gap.

Safety Bottom Line

Either option is safe when installed correctly by a licensed electrician with a TSANB permit. The hardwired option simply removes one potential failure point. If you're staying in your home long-term, hardwire it. If you're renting, plan to move, or want flexibility, a NEMA 14-50 outlet is a reasonable compromise.
