Why Your Multimeter Won't Save You
There is a dangerous misconception that owning a voltage tester makes someone an electrician. We see it all the time: a homeowner watches a video, buys a cheap multimeter, and decides they can fix a flickering circuit. Sperry Electric LLC is here to challenge that confidence. Diagnosing electrical faults is not about seeing if the light turns on; it’s about understanding the invisible and deadly flow of current. The stakes are too high for amateur hour.
Let’s be real about what you can’t see. A simple "open neutral" can cause 120-volt circuits to spike to 240 volts, instantly frying every appliance plugged into them. Can you identify a shared neutral on a multi-wire branch circuit before you disconnect it and get shocked? Do you know how to trace a ground fault that is leaking current into your plumbing system? These are scenarios that kill DIYers every year. A meter might tell you that you have voltage, but it won't tell you why your neutral wire is hot or why your grounding bond is floating.
The "fix" often makes things worse. We frequently find dangerous handy-work where someone replaced a breaker that kept tripping with a larger one. They stopped the tripping, but they removed the safety limit of the wire, turning the wiring inside the wall into a heating element. That isn't a repair; it’s a fire trap. The breaker was tripping for a reason—to save your life. By bypassing that protection without understanding the root cause, you have compromised the safety of the entire structure.
True diagnostics require experience and intuition. We know where to look because we have seen thousands of failure points. We know that the problem in the bedroom is often caused by a loose wire in the outdoor receptacle exposed to rain.
