The problem
A new EV without a Level 2 charger at home is a half-finished purchase. You'll plan trips around DC fast chargers, ration battery in winter, and lose the single biggest reason to own one — waking up to a full pack every morning.
A residential Level 2 install is one dedicated 240V circuit pulled from your panel to the install location, terminated to manufacturer spec, and inspected. Sounds simple — but panel headroom, conduit routing, and load calculation get it wrong often enough that bad installs are common. We assess capacity first, then run the circuit cleanly, then torque every termination to the published spec.
“We don’t hand off jobs to strangers. Every breaker, every outlet, every permit — that’s us.”
Documented work
Recent ev chargers.
Tesla Wall Connector — 60A breaker, 48A continuous, single-charger circuit. 
Wiring panel open before close-up. THHN copper landed and torqued. 
Every termination torqued to manufacturer spec — 25 in-lb at the breaker.
Why Northern
What you’re actually paying for.
Every major brand installed
Tesla Wall Connector, ChargePoint, Wallbox, Emporia, Grizzl-E — no brand-specific certifications required for code-compliant installation.
Torqued to spec, every termination
Loose terminations cause the bulk of EV charger failures. We torque to the manufacturer's published value with a calibrated torque wrench and document it.
Load calculation included
Panel headroom calculated to NEC 220 before quoting. If your panel can't carry it, we'll quote the service upgrade alongside the charger — under one permit.
Single-visit completion
Most Level 2 installs complete in 4-6 hours on a single visit, including the permit pull and inspection scheduling.
Implementation
What the day looks like.
A typical residential install runs a dedicated 50A or 60A circuit in 1" EMT conduit from the panel to the install location. Wire is THHN copper, sized to NEC 310 for the run length and ambient temp. Charger mounts to a stud or backer block, terminations are torqued and recorded, and the unit is bonded to ground through the conduit system. Most installs are walk-through, quote-same-day, and complete the following week.
If your panel can't carry headroom for a 50A circuit, we'll quote a service upgrade alongside the charger — both pulled under one permit.
Frequently asked
The questions that come up before booking.
Can I bring my own charger?
Yes — any UL-listed Level 2 charger we'll install. Bring the unit and the install manual; we'll spec the circuit to the charger's published amperage.
What size circuit do I need?
Tesla Wall Connector and most modern chargers spec a 60A breaker on #6 copper for 48A continuous output. ChargePoint and some others run 40A. We size to the manufacturer spec, not a one-size-fits-all default.
What if I move and want to take the charger?
We can wire the install with a NEMA 14-50 outlet behind a quick-disconnect plug. Takes the charger with you, leaves the circuit ready for the next owner.
Do I need a permit for a residential EV charger?
Yes — every MA, NH, ME, and VT town we work in requires a permit and inspection for new 240V circuits. We pull it, you don't have to think about it.
Can two EVs share one charger or one circuit?
Yes. Tesla Wall Connectors can load-share on a single circuit (up to 4 chargers). We size the breaker and feeder accordingly.
