Double lugging is when two wires are placed under the same screw on a circuit breaker or on the neutral bus in an electrical panel. Double-tapping is normally done by a homeowner or a handyman who knows just the basics of electrical work.
What is current? What is voltage? What is the difference between voltage and current? How are voltage, current and resistance related? I will explain these concepts by comparing electricity flowing through a wire to water flowing through a water hose.
One of the few common light configurations on a three-light tester is one that is labeled as a “Hot-Ground Reverse.” This is a very rare situation that would be very difficult (and dangerous) to achieve.
This will be just a quick post to explain something that I have recently discovered. The low cost, 3-light outlet testers that many home inspectors and electricians use can give you different readings depending on whether or not something is plugged
Circuit breakers protect our homes by tripping and opening up the circuit to stop the flow of electricity if too much current flow is detected. Most circuit breakers have two separate mechanisms that each work in different situations to trip the breaker. These two mechanisms are a thermal trip and an electromagnetic trip.
If you are a home inspector or an electrician and are using one of the low-cost, three-light outlet testers to check electrical outlets, you could be missing a wiring problem that you should be aware of. These three-light outlet testers will NOT indicate a hot/neutral reverse situation if the outlet being tested is not grounded.
