20-amp circuits handle higher electrical loads and use thicker 12-gauge wire versus 14-gauge for 15-amp circuits. Kitchens, bathrooms, and appliance outlets typically require 20-amp circuits for safety.How long does EV charger installation take?
Most Level 2 EV charger installations take 2-4 hours depending on electrical panel capacity and distance from the installation point. Panel upgrades may add additional time.Why does my circuit breaker keep tripping?
Circuit breakers trip due to overloaded circuits, short circuits, or ground faults. Frequent tripping indicates electrical problems requiring professional diagnosis to prevent potential fire hazards.What electrical permits do I need in Massachusetts?
Most electrical work requires permits from your local building department. Licensed electricians typically handle permit applications and ensure work meets current Massachusetts electrical codes and safety standards.Can I install GFCI outlets in older homes?
