Simultaneous Level 2 Charging for a Two-Vehicle Household

When two electric crossovers entered daily family service, cord swapping and delayed morning commutes became an everyday friction point. The property featured a standard 200-amp residential electrical panel already powering air conditioning, a heat pump water heater, and modern kitchen circuits. Rather than undertaking an extensive and costly utility service line rebuild, our certified electricians designed a coordinated dual-station system that leverages smart power distribution, dedicated steel conduit runs, and balanced phase routing to charge both vehicles quickly and safely every night.

Technical Stages from Load Evaluation to Final Commissioning

Operating two 48-amp EV stations concurrently demands up to 96 continuous amps, which could trigger main breaker trips during extreme summer cooling cycles. The Mountmixazor engineering team verified total baseline household consumption under NEC 220 rules, confirming that smart paired load sharing would safely maintain peak demand inside the homeowner’s 200-amp service threshold.
