120v and 125v outlets are nominally identical. You must have something miswired, or you have a rare faulty unit. Be sure you have power connected to the LINE side. What Read more

To some degree, Nickel Metal Hydride (NiMH) is interchangeable with Nickel Cadmium (NiCd) — with caveats. The issues related to replacing NiCd with NiMH are the charge methods, the discharge Read more

These unwanted perturbations (if not controlled) can couple directly into the circuit and cause instability or damage. In this case, the bypass capacitor is a first line of defense. It Read more

The battery will have a high current discharge and will heat up. It is recommended to preserve the battery against strong shocks. In case of usage: This occurs when a Read more

The main two reasons that would cause a capacitor to explode is Reverse polarity voltage and Over-voltage (exceeding the voltage as little as 1 – 1.5 volts could result in Read more

as long as the phase conductors are on different “phases” it’s fine. Recent code requires them to be on a double pole breaker though. I do it as much as Read more

Never use power strips or surge protectors for high-power capacity items such as, space heaters, dehumidifiers, or other high capacity appliances. Plug them directly into a wall outlet. Can I Read more

You would most likely damage your meter, and could possibly create an “over-current” situation in the circuit you’re trying to test. Can I use multimeter on live circuit? Testing whether Read more
