Every house comes with an electrical switchboard. It protects the electrical wiring system at your residence. As part of your home maintenance checks or when doing your next renovations, have a look inside your switchboard. This is where the main power switch, plus a number of fuses, or circuit breakers are placed. Each fuse or circuit breaker connects completely to another area of wiring in your home. Appears to be electrical fault accurse, the fuse will blow or perhaps the circuit breaker will trip, cutting off the power preventing overloading or household fire. A circuit breaker may be switched back on, whereas each fuse blows it must be substituted with a new one.
Always turn off the principle power switch if you are changing a fuse together with turning off all electrical appliances and lightweight switches that are connected to the blown fuse. Replace the fuse while using correct current rating. Excessive a current rating will cause excessive current to circulate through the circuit. Overheating and even fire can occur.
If a fuse keeps blowing, find one of the many licensed Auckland electricians. There might be hidden electrical problems that you won’t have picked up. If possible, swap the little fuse within your switchboard with plug-in circuit breakers of the same rating, because these are safer to use and don’t require replacing.
Find out what electrical switches and appliances the fuse or circuit breaker protects. Switchboards are typically labelled for easy identification. Or else, ask an electrician to do this for you. This can save you time in identifying a blown fuse or which circuit breaker to modify off.
How to Replace a Fuse
Follow these steps:
1. Turn off the main power switch at the switchboard.
2. Look from the switchboard for a list of where each circuits every fuse connects to.
3. If it’s not obvious which fuse has blown, inspect each fuse individually.
4. Once you have found the blown fuse, switch off lights and unplug all appliances on that circuit.
Replace the fuse wire. Ensure you use the correct current rating fuse wire. The existing rating is generally indicated for the front of the fuse carrier.
Lighting circuits typically use 5 amp, however, not greater than 10 amp fuse wire.
Socket outlets use 10 amp but not greater than 15 amp fuse wire.
Large appliances make use of a larger size fuse.
Be sure to cut off any excess fuse wire.
5. Put the fuse back in its slot and reverse on the main power switch.
6. If your fuse blows again, call a qualified electrician.
What to do if a Circuit Breaker Trips?
If your power goes off because your circuit breaker has tripped adopt these measures:
1. Switch off lights and unplug all appliances within the faulty circuit.
2. Push the operating lever to your “on” position, or push in the button on the circuit breaker.
3. When the circuit breaker continues to trip, it’s time to get hold of one of the many licensed Auckland electricians.
