Safety components which an electrician Essex needs to know about
Unless you are a qualified professional you must always use a trained electrician Essex to carry out any electrical work you need doing. Do not attempt to do any work yourself as it is potentially dangerous. However it is always useful to have a bit of knowledge so here are some essential safety components your electrician Essex will use on a daily basis:
The fuse is something you do not have to be an electrician Essex to be familiar with as it is used in just about every household device powered by electricity. It is a type of sacrificial protection device (something designed to fail when put under excess stress to prevent other parts of the system being affected) and was one of the pioneering inventions of Thomas Edison. Each fuse contains a metal strip which melts when excess current passes through it, thus breaking the circuit and preventing the current from going any further. It is a single use component.
An electrician Essex will tell you that a circuit breaker is like a fuse but reusable. They vary dramatically depending on their application but they protect against a short circuit or an overload by breaking the circuit. This is done by having contact pad which are sprung apart when an overcurrent or short circuit is detected. A varistor – which you may know as variant resistor – protects circuits against excessive transient voltages. Put simply, these conduct excessive voltage to keep it away from vital components. A spark gap is another invention, which consists of two conducting electrodes separated by a gap designed to allow a spark to pass between the two. They are commonly used in spark plugs. Any electrician Essex will tell you that there are far more components than are listed above, but an understanding of these core devices helps you make an informed decision.
