Electricity Made Easy
Are you feeling intimidated by all the electrical jargon flying around lately?
I mean, what the heck is an RCD? And watt - sorry, what - is a volt? We get it, we really do. In our day-to-day lives, most of us don’t need to understand the ins and outs of our fuseboxes (and some of us don’t even know where it is!) But wrapping your head around a few simple terms could make your life easier and safer.

‘Amps’ is the measure of current flowing in an electrical circuit.. You should think of electric current as the rate of flow of water through a hosepipe. The more water flowing through the hosepipe, the stronger (higher) the current is.
‘Volts’ is the measurement of electric pressure that causes electric current to flow. In keeping with the earlier example, you could think of volts as the water pressure in the hosepipe, which makes the water flow.
Amps multiplied by Volts equals Watts, which is the measurement of how much power is used in an electrical circuit. For example, the higher the wattage of an appliance is, the more power is used to run it. In terms of the hosepipe example, this would refer to the amount of water being released.
Ever wondered what an RCD is? It stands for Residual Current Device, and switches off the electricity automatically if there’s a fault. It’s designed to prevent you from getting a fatal electric shock and is quite literally a lifesaver. An RCD constantly monitors the electric current flowing through one or more circuits it is used to protect. If it detects electricity flowing down an unintended path, such as through a person who has touched a live part, the RCD will switch the circuit off very quickly, significantly reducing the risk of death or serious injury. Although RCD protection reduces the risk of death or injury from electric shock, it does not reduce the need to be careful. Have your wiring checked at least once every 10 years to ensure that it’s safe, and test your RCDs every three months. If you find a fault with your wiring or an appliance, stop using it immediately and contact a registered electrician.
If you are a landlord, you should have the electrical wiring in your rental properties checked at least every five years.
We’ve all got one, but what exactly are they? Well, it’s pretty much what it says on the tin: a box that houses the fuses or circuit-breakers in a property – sometimes called a consumer unit. It’s where the electricity in your home is controlled and distributed - if you don’t know where yours is, make sure you find out in case you ever need to turn the electricity off in an emergency. Your fusebox will contain three things: the main switch, fuses and/or circuit breakers, and RCDs. Main Switch - this allows you to turn off the electricity supply to your home. You might have more than one mains switch, so make sure you find out exactly how many you have and where they are. RCDs - you’re already an expert on these! Circuit Breakers - these are automatic protection devices in the fusebox that switch off a circuit if they detect a fault. They are similar in size to fuses, but give more precise protection. When they ‘trip’, you can simply reset the switch - but make sure the fault is corrected first!
