Insights, tips, and guides on power management and energy efficiency
Before buying a Level 2 charger, two numbers matter: what it does to your electrical service under the NEC existing-dwelling calculation, and how many hours it takes to refill your car. We work both for a typical house under NEC 2023 and NEC 2026.
Generator sizing is a load calculation with a rule from NEC 702 on top. We run three houses through the engine, size each one two ways, and show what each size burns in a three-day outage.
