EV Charger Installation in Southern NH
—VETERAN OWNED—
Serving Homeowners in Southern NH
A veteran-owned business with over 30 years of experience, Jolt Electric & HVAC installs Level 2 EV chargers for homeowners and businesses throughout Southern New Hampshire. We handle everything from the panel capacity check to the final connection, so your charger works correctly from day one.
Level 1 charging, plugging your car into a standard 120-volt outlet, works in a pinch but it's slow. Most electric vehicles gain 3 to 5 miles of range per hour on Level 1. A Level 2 charger operates on 240 volts and delivers 20 to 30 miles of range per hour, meaning most drivers wake up to a full battery regardless of when they plugged in the night before. For NH commuters dealing with longer drives to Manchester, Nashua, or Boston, that difference is the gap between arriving with range to spare and watching the battery percentage all day.
What Level 2 EV Charger Installation Involves
Installing a Level 2 charger isn't as simple as mounting hardware on a wall. There's real electrical work behind it, and doing it right means your charger runs reliably for years without nuisance tripping or degraded performance.
Panel Capacity Check
Before we install anything, we evaluate your electrical panel. A Level 2 charger draws 30 to 50 amps, depending on the unit. If your panel is already close to capacity or still running 100-amp service, we identify that upfront and walk you through options, whether that's a breaker panel upgrade or load-management strategies that let your current panel handle the new circuit safely.
Dedicated Circuit Installation
Every Level 2 charger needs its own dedicated circuit. We run the circuit from your panel to the charger location, install the appropriate outlet or hardwire the unit, and size the breaker correctly for the charger's draw.
Shared circuits cause nuisance trips and are a code violation. The circuit also needs to be rated for continuous load, which means the breaker is sized at 125% of the charger's amperage draw, not just the charger's nameplate rating.
Charger Selection and Mounting
We work with all major EV charger brands and help you choose a unit that fits your vehicle, your usage pattern, and your budget. For homeowners, we typically install in garages or on exterior walls. Businesses looking to add employee or customer charging spots are handled through our commercial charging installations.
Outdoor and Cold-Weather Installations
If your charger will be mounted outside a garage or on an exterior wall, the installation needs to account for NH winters. We use weatherproof enclosures, outdoor-rated wiring, and conduit routed to avoid ice buildup.
GFCI protection is required for outdoor charger outlets and is part of every installation we complete. Getting this right upfront prevents freeze damage and nuisance tripping in cold weather.
