Common questions for Ground Wire Installation in Castle Hills
Do I need to add grounds to my old two-wire circuits?
Code does not retroactively require grounding existing two-wire circuits. NEC allows a GFCI receptacle on an ungrounded circuit (marked "No Equipment Ground") for shock protection without rewiring. Best practice for any sensitive electronics is full grounding via rewire.
How many ground rods do I need?
NEC requires a single ground rod or a grounding system that meets resistance requirements. In practice, two rods 6 feet apart is the standard install because measuring resistance on a single rod is rarely done.
Why does proper grounding matter?
Grounding gives ground faults a low-impedance path back to the source so the breaker trips quickly. Without grounding, a fault can leave a metal surface energized at line voltage. Grounding is the difference between a tripped breaker and a shock hazard.
Can I retrofit grounding without rewiring?
Sometimes. GFCI receptacles provide shock protection on ungrounded circuits per NEC. Some homes have metal-conduit-fed circuits where the conduit provides the ground path. True grounding for sensitive electronics requires either of those or new cable.
How much does grounding work cost?
Service grounding electrode upgrades are smaller jobs. Adding equipment grounds to multiple circuits or full rewires for grounding are larger. We quote in writing.
