What fuse should i use

For AGC cylindrical fuses, there are two distinct types of fuse holders to choose from. How many watts can a 5 amp fuse take? Multiply the voltage by the amps and this will give you the maximum number of Watts you can place on the circuit. If your lighting circuit at home is protected by a typical 5 amp fuse you can multiply this by the voltage to get Watts. How do you measure a fuse? Before you test a fuse with a multimeter, turn off the equipment and remove the fuse by pulling it straight out of its slot.

Turn the meter to ohms, then touch the positive and negative leads together and check the reading. Next, put one lead on each end of the fuse and check the reading. How do you size a fuse? What size fuse should I use for my amp? The Right Car Amp Fuse Size If your amplifier has an internal fuse, then your inline car amp fuse should be a little bit larger. For instance, you might want to use a 25 or 30 amp inline fuse if your amp has an internal 20 amp fuse.

What are the 3 types of fuses? The low voltage fuses are divided into five types such as rewirable, cartridge, drop out, striker and switch fuses. Image Source. Rewirable Fuses. Cartridge type Fuses. D-type Cartridge Fuse. Link Type Fuse. Blade and Bolted type Fuses. Is it OK to put a 5 amp fuse in a 3 amp plug? No, it's quite safe. I think I've seen lamps with 13 amp fuses anyway. He has to use 65 amp fuse.

So I am trying to connect 2 x 55w lights on my car, would I add the two together and do the math that way? Any recommendations for wire size would be appreciated as well.

I suggest 14 gauge wire, and a 15 amp fuse. So im going to fit 4 x 3. Can you recommend what size wire and fuse please. I suggest 18 to 20 gauge wire, and a 2 amp fuse. Ive just had an electritian use 12 gauge wire on a 12v set up on a RV im building. I have calculated the amps for the fuses so thats all o i think but is the 12 guage wire a problem. A rocker switch for each half 10 led lights, plus flasher At times only one side will be lit, other times both at once.

Can use a single 1 amp fuse? Can 18AWG wire be used to run them in series? I would like to know what size inline fuse to use to protect the charger from over heating burning out the transformer if a shorted battery is plug in.

It has now burned up 2 different relay blocks. Was thinking of using 10 or 12 gauge wire but my concern was the connection between the add a fuse wire which all seem to be 16 awg and the 10 gauge wire. Will this be an issue since the wire will go from 16 down to 10 right out of the circuit? Each lamp is 10 watts.

Run is less than 5 feet. From this blog, I assume that on a 12v system drawing 20 watts is equal to 1. Is 18 to 20 gauge wire, and a 2 amp fuse correct? Thank you. Im runing 2- 30 Watts led spot lights on 20 awg wire directy from 12volt car battery what size of fuse do i need. Have a question. A 12v domestic R solar electric has three 10w lamps and 30w black and white television.

Determine the; a Size of a fuse required. I bought three 1 watt screw led amber lights from you and wired with an add a fuse to my fog lights. What size fuse should I use for the led. Each light draws about 37 mA 12vdc, so thats a total of mA 0. Wire size 22 gauge. Each is. Going to rocker switch. Do I use a 20amp fuse? And what size relay? I have a 40 amp relay, is that ok!

Please double check the actual current draw. Perhaps you mean each one draws 0. If each light draws 0. I have installed a 12A W light bar installed. According to this, I should use a Is my math correct? Its possible your light bar draws less than watts of power. So at I was thinking about adding a 6 space fuse panel to my truck for small amp accessories. My thought was an 80 amp split circuit relay to power the accessories when key is on the length of the run is no longer than 4 ft.

The relay I was looking at has size 12 awg wire. My question is, is this possible and if so what size fuse should I use to protect the circuit from the battery and what is the smallest amperage should I use the close the relay. I am planning to install Hazard Lights on a Classic car.

I have obtained a perfect wiring diagram to achieve this. This diagram shows an in-line fuse to protect the circuit. The wire required should be able to carry a current to flash 4 lights each containing 21W bulbs.

I plan to make any wire connections using 6. What gauge wire should I use and what size fuse should I use for this wiring? Thanks in advance for any help you can give me. Great table, thanks for the article.

Phil Suslow says:. November 12, at pm. Douglas Adams says:. As a rule of thumb, fuses are rated according to the power rating of the appliance. If you have to replace a fuse, it's essential, having checked and corrected the reason for the fuse blowing, to replace it only with another of the same rating.

A common UK plug is generally fitted with a 3A or 13A fuse. Plugs for appliances rated between about watts and watts the maximum rating of a wall socket should be fitted with a amp fuse coloured brown. Manufacturers have now standardised plug fuse ratings to be either 3A or 13A. However, 5 Amp fuses are still used in some older equipment and are available to buy. We have developed a plug pin gauge which allows you to perform some quick checks to help identify a sub-standard or counterfeit plug.

If you'd like to order one, click here. With the plug removed from the socket, check the cable: Is the cable securely attached to the appliance and the plug? Is the cable cut, nicked or damaged in any way? There should be no joints and no repairs with insulating tape. Then, check the plug: Look for cracks or damage on the casing.
