Earth leakage and the diagnostic tool | Megger asked: I've been having a few problems recently with nuisance tripping of RCDs and RCBOs.In most cases, the devices themselves are fine, so there really is leakage to earth, but finding out where it's occurring is a real pain – and it's time consuming.
Is It Safe to Put Insulation Behind a Gas Fireplace? | eHow fireplaces require venting to outdoors. Depending on the home's construction and fireplace placement, these vents may run directly through an outside wall or up through an attic. In either case, the manufacturer's instructions must be followed regarding insulation contact with the vent pipe as well.

Transformers - Transformer Components | MISUMI transformer is a device that changes the voltage, also called a power transformer. Performs the step-down and step-up of AC voltage, and makes adjustments necessary for use in electronic devices. The transformer has a structure in which a primary coil and a secondary coil are wound around an iron core.
