I reset my circuit breaker, but there's still no power. What should I do?

When you successfully flip a tripped circuit breaker back to the "On" position but electrical power fails to return to the rooms or outlets on that branch circuit, it indicates that the electrical continuity remains broken elsewhere in the system. Common causes include a downstream Ground Fault Circuit Interrupter (GFCI) receptacle that has tripped independently and must be manually reset at its own face buttons, a loose wire nut or terminal connection inside a junction box or switch enclosure that disconnected during the electrical fault, a tripped multi-pole breaker, or a main service panel feed issue. You can troubleshoot power failures safely by using a non-contact voltage tester to trace where line voltage stops. You can verify that your corrective action is successful when locating and resetting a tripped GFCI outlet, securing loose junction box wire nuts, or restoring faulty switch connections brings the circuit back to full operational status and restores power.
