Electrical Troubleshooting

Find the fault. Fix it right.

Breaker that won’t stay on, half the house dark, a circuit that’s dead for no reason you can see. I trace the actual fault instead of guessing and swapping parts, anywhere around Lake Keowee.

What this is

I trace the break. I don't guess.

Most electrical problems have one real cause, and the fix is fast once you find it. The hard part is finding it. A loose neutral, a nicked wire behind drywall, a corroded connection in a junction box, a buried line that took a shovel. Guessing means replacing good parts and billing you for it.

I work the circuit methodically with the right test gear. Continuity, voltage drop, fault distance on a cable tester. I read what the wiring is actually telling me, find the break, and show you what I found before I fix it. No mystery, no parts cannon.

Finding a break in a wire, on camera

This is the exact tool and method I use to pin down a break in a run, a Klein Tools ET450 cable tester reading how far down the wire the fault is. No tearing into walls to go hunting.

When to call

Signs it's a fault, not a fluke

If any of these are happening, something in the wiring needs to be traced, not ignored until it gets worse.

Breaker keeps tripping

It resets, then trips again, sometimes with nothing plugged in. That’s a short or ground fault somewhere on the circuit, not a coincidence.

Dead outlets or a dead circuit

Half a room or a whole circuit goes dark while everything else works. The break is somewhere upstream, and it’s findable.

Lights flicker or dim

Flickering when the AC kicks on, or lights that pulse for no reason, usually points to a loose connection or an overloaded neutral.

Warm plates or a burning smell

A switch or outlet cover that’s warm, or any faint burning smell, means a connection is arcing. Shut it off and call. This one doesn’t wait.

GFCI won't reset

An outlet or breaker that trips the second you reset it is reading a real ground fault. The fault is real even when you can’t see it.

It only happens sometimes

Intermittent faults are the worst to chase on your own. The right meter finds them whether they’re acting up at the moment or not.

How it works

How I find a fault

1

Listen and isolate

You tell me what it’s doing and when. I map the circuit and narrow the problem down to a section instead of the whole house.

2

Test with the right meter

Continuity, voltage drop, and a cable tester that reads how far down the wire the break is. The video above shows exactly this on a Klein ET450.

3

Locate and repair

I find the break, show you what caused it, and fix it the right way. Proper splice, proper connection, to code.

4

Verify and clean up

I confirm the circuit reads right under load, document what I found, and leave the work area clean.

Why Sunset Electric

Local, licensed, and actually diagnostic

Plenty of people will swap a breaker and hope. Finding the real fault takes a licensed electrician, the right tools, and someone who knows how the homes around this lake are wired.

FAQ

Troubleshooting questions, answered straight

Have a question not listed here? Call or text (864) 436-8680 — I’m happy to talk through it.

A cable fault tester reads the electrical distance to the break, so I can tell you how far down the run the problem is before opening anything up. Between that, continuity testing, and tracing the circuit, I can usually pin a hidden or buried break to a small area instead of tearing out a wall.
Could be either, and the test tells us which. If it trips with the circuit unloaded, that’s a short or ground fault that needs to be traced. If it only trips under heavy load, the circuit may be overloaded or the breaker is failing. I’ll know quickly which one you’ve got.
I’ll tell you the diagnostic cost up front before I start, and what it covers. If the repair is simple and I do it on the same visit, I’ll tell you how that works too. No surprise line items.
Usually, yes. Most faults are a repair I can make on the spot once I’ve located them. If it needs a part I don’t carry or a permit and inspection, I’ll lay out the plan and timeline before any work starts.
