What size fuse do I need for an outside light?
You should have a 3A fuse for the light.
Do outside lights need to be on their own circuit?
In 90% of cases, the outdoor lighting is a complete afterthought to the building. Ideally, the supply to the garden lighting installation should be an independent circuit with an independent RCD/RCBO so that, if tripping issues do occur, they don’t affect the rest of the installation.
Can you use a 3 amp fuse instead of a 5 amp?
A 3A fuse was used for a reason. If so, yes, you can replace a 3A fuse with a 5A fuse. Never replace a blown fuse with a higher-amp fuse. Always replace the fuse with one with the specified amp rating.
Can interior and exterior lights be on the same circuit?
1 Answer. Yes, interior and exterior lights can be on the same circuit.
How big of a fuse do I need for 10 watts?
10 watts at 12 volts is equivalent to 0.833 amps, so yes, a single 1 amp fuse should be fine. You can use 18 gauge wire. It doesn’t make sense to wire them in series. You should wire them in parallel.
Where do you find the fuse rating on a light?
You’ll usually find the fuse rating on the side of your fuse, which will be given in amps. Fuse rating is the amount of current needed for the fuse to blow or break. When this happens, it stops the electrical power from flowing through the electrical circuit.
What should the fuse rating be for a 12 volt?
The fuse rating should lie somewhere between these two values to allow normal operation but blow on overload. For example, if the normal expected current draw is 10A and the cable size is 25A, then a fuse rated at 15A would be appropriate.
How big of a fuse do I need for a stage spotlight?
It is extremely unlikely your lights will need more than a 5 amp fuse. A 5 amp fuse will let use 1000W which would be an extremely bright bulb – a stage spotlight perhaps? DO NOT use a 13 amp fuse. It’s likely the lighting circuit will not take it and whatever is causing the short circuit could start a fire.
What should fuse rating be for lighting circuit?
For the lighting circuit, the fuse current rating should be minimum 2 times the full load current of the total number of lighting. For individual circuit, the fuse rating should be 1.5 times of the full load current.
10 watts at 12 volts is equivalent to 0.833 amps, so yes, a single 1 amp fuse should be fine. You can use 18 gauge wire. It doesn’t make sense to wire them in series. You should wire them in parallel.
How big of a fuse do you need for a hot water heater?
So, for example assuming the Power of your heater is 1200W and the UK mains voltage is 230V: You will therefore require a minimum of a 6 Amp fuse in your plug.
It is extremely unlikely your lights will need more than a 5 amp fuse. A 5 amp fuse will let use 1000W which would be an extremely bright bulb – a stage spotlight perhaps? DO NOT use a 13 amp fuse. It’s likely the lighting circuit will not take it and whatever is causing the short circuit could start a fire.
