EV charger installation in a Queens garage

Problem

Homeowner needed reliable Level 2 charging but the detached garage had only general lighting power fed from the main house.

Site conditions

• Detached garage with existing conduit path and limited interior wall space
• Main panel inside the house with modest spare capacity
• Cold-weather exposure requiring appropriate outdoor-rated equipment

Diagnosis

Load calculation confirmed capacity for a 40A EV circuit. Existing conduit was adequate for new conductors with proper derating and terminations.

Work performed

• Pulled new conductors through existing conduit to the detached garage
• Installed a dedicated 40A breaker and EV receptacle/charger mount with proper working clearance
• Tested voltage and charger commissioning, confirming GFCI-protection requirements

Safety / code notes

• Used outdoor-rated components and ensured drip loops where exposed
• Verified GFCI/grounding per manufacturer and code requirements
• Labeled panel for the new EV circuit and provided homeowner usage guidance

Outcome

Homeowner now has dependable overnight charging with a dedicated, labeled circuit and code-compliant installation ready for future vehicle upgrades.
