FAQs
What should I do if my circuit breaker keeps tripping even after I reset it?
Frequent tripping generally indicates an underlying problem such as an overloaded circuit, a short circuit, or a ground-fault. First, unplug or switch off all devices on the affected circuit and try resetting the breaker again. If it holds, plug the devices back in one at a time to identify the culprit. If the breaker trips immediately after you reset it—even with everything unplugged—there may be a wiring fault or a failed breaker. At that point, shut off the main breaker for safety and contact a licensed Reliance electrician for diagnostic testing with an ammeter and insulation-resistance meter. Continuing to reset a breaker that repeatedly trips can overheat the wiring and pose a fire risk.
Why are some outlets in my home not working while others are fine?
Dead outlets are most often caused by tripped GFCI receptacles, loose back-stab connections, or a failed breaker. Start by locating and resetting all GFCI outlets, as they often protect multiple downstream receptacles. If that doesn’t restore power, turn off the breaker feeding the circuit, remove the cover plate, and check for loose wires, particularly wires pushed into back-stab holes rather than secured under terminal screws. Tighten or re-terminate as needed. If multiple outlets are dead, the issue may lie in the first outlet of the run or at the breaker itself. Any signs of burning, melted insulation, or buzzing require you to discontinue DIY work and arrange for professional service from Reliance to avoid shock or fire hazards.
How can I identify and safely fix a short circuit in my home wiring?
A short circuit occurs when a hot conductor contacts neutral or ground, creating a sudden current spike that trips the breaker. Symptoms include an immediate breaker trip or visible sparks when turning on a device. To pinpoint the fault: (1) Turn off the affected breaker. (2) Disconnect all loads on that circuit. (3) Use a multimeter in continuity mode between hot and neutral/ground; if continuity is present with all devices removed, the short is in the fixed wiring. Inspect cable runs for damaged insulation, crushed conduit, or rodents. Replace any compromised cable with correctly rated wiring. If continuity disappears with wiring isolated, reconnect devices one at a time until the meter shows a short—indicating the defective appliance. Because troubleshooting shorts can expose live conductors, Reliance recommends homeowners call a qualified technician unless they are fully comfortable with lockout/tag-out procedures and local code requirements.
What are the signs that my electrical panel needs an upgrade or repair?
Warning signs include warm or hot breakers, a burning odor, visible corrosion, buzzing sounds, or frequent nuisance tripping. If your panel is over 25 years old, still uses fuses, or has obsolete brands (such as Zinsco or Federal Pacific Stab-Lok), replacement is strongly advised because of documented safety issues. Modern households also require higher amperage capacity to run HVAC, EV chargers, and induction ranges. A Reliance electrician will perform a load calculation per NEC Article 220, inspect conductor sizing, and, if necessary, recommend a panel upgrade or installation of sub-panels with AFCI/GFCI protection to ensure both safety and future expandability.
Can I troubleshoot and repair flickering lights myself, and when should I call a professional?
Intermittent flickering can stem from loose lamp sockets, degraded dimmers, or voltage fluctuations. Begin by tightening the bulb and replacing it with a known good bulb. Next, ensure that dimmer switches are rated for the bulb type (LED, CFL, or incandescent). If the issue affects multiple fixtures or occurs when large appliances cycle on, you could be experiencing voltage drop due to overloaded circuits or a failing service neutral. Use a voltmeter to record voltage at the panel during appliance start-up; variation greater than ±5 % indicates a problem that requires utility or service-entrance repair. If you notice lights dimming throughout the house, sparks behind switches, or a buzzing breaker, stop troubleshooting and contact Reliance immediately, as these symptoms can precede electrical fires.
What safety precautions should I take before attempting any electrical repair?
1) Turn off the breaker to the affected circuit and confirm power is off using a non-contact voltage tester and, where possible, a multimeter on both hot-to-neutral and hot-to-ground. 2) Lock out and tag out the breaker to prevent accidental energizing. 3) Wear insulated gloves and safety glasses, and use insulated tools rated to 1,000 V. 4) Stand on a dry, insulated surface to reduce shock risk. 5) Never touch plumbing or grounded metal while working on wiring. 6) Follow manufacturer instructions and local electrical codes; when in doubt, consult the NEC. If the work involves the main service panel, aluminum wiring, or any signs of overheating, do not proceed—call a licensed Reliance electrician. Electricity can cause severe injury or death; safety should always be the top priority.
