3 Calculators NEC 625 / 220.12 / 300.5

EV Charger Load Calculator

NEC Article 625

Calculate circuit breaker size, conductor size, and circuit load for EV charging equipment per NEC 625.42. EV charging is classified as a continuous load.

Lighting Load Calculator

NEC 220.12

Calculate general lighting load and minimum number of branch circuits required per NEC Table 220.12 based on occupancy type and square footage.

Underground Cover Depth Calculator

NEC 300.5

Determine minimum cover depth for underground wiring per NEC Table 300.5. Results vary by wiring method and installation location.
