The maximum permissible load of a lighting circuit is 1200w or 12* 100 watt lamps3 AMPFor appliances up to 700 watts, such as table lamps and alarm clocks3 more rows.

## How many watts can a 16 amp fuse take?

Your MCB can hold up to 16 Amps and the voltage applied will determine how many Watts. The formula is simply Amps multiplied by Volts equals Watts. In the case of a 120V supply this means 1,920 Watts for a 240V supply it will be 3,840 Watts.

## How many watts can a 40 amp fuse handle?

9,600 watts40-amp 240-volt circuit: 40 amps x 240 volts = 9,600 watts. 50-amp 240-volt circuit: 50 amps x 240 volts = 12,000 watts.

## Can I use a 3a fuse in a 13a plug?

BS1363 has standardised on just two preferred fuse ratings, 3A and 13A, however any fuse rating up to 13A can still be used.

## Can I put a 3 amp fuse in a 10 amp plug?

The 13A fuse in place of a 10A fuse wouldn’t directly cause any problem – but then, if there’s a problem with the appliance you’re using, or if you plug in too many things and the current goes over 10A but under 13A, then under the new fuse the extension lead will keep working whereas the old fuse would have blown.

## What amp fuse do I need for LED lights?

75mm is good for about 7.5 amps max. I generally like to have at least 100% extra rating so a 3 amp fuse max is what i would use. This should be plenty for 4 leds. If you have working leds but blow a 10A fuse i think your wiring needs checking and you will probably find your fuse is directly across the battery.

## How do you size a 12v fuse?

Find the size of fuse by multiplying the amps required by the device (2) by 1.5. 2×1.25 = 2.5 then we will round up to the nearest fuse size (in multiples of 5 amps) which would call for a 5 amp fuse.

## What are 5 amp fuses used for?

5A Fuse. Used mainly for lighting circuits.

## What size fuse do I need for a 2000 watt amp?

Add all the fuse values together and you have the max the amps can draw. So if for exapmle the 2000w amp has 2-80a fuses..and the 300w has a 30a fuse..

## How many outlets can I put on a 10 amp circuit?

Always the big question, how many lights on one breaker Well NEC code does not have it listed that way. By rule of thumb you would stick with 8 to 10 outlets and or lights per breaker. Now this is of course they are 120 volts 60 Hz (USA or Canada).

## Can I replace a fuse with a higher amp?

In general, NO. Replacing a fuse with a higher-amp fuse is a very bad idea and can lead to fires. Fuses (and circuit breakers) are rated such that they blow or trip before any part of the circuit gets to a dangerous current. … Fix the underlying problem, and you won’t have any more blown fuses.

## What is 3 amp fuse used for?

Different types of fuses Plugs for appliances rated up to about 700 watts should have a 3-amp fuse (coloured red). For example: 3A Fuse – Table lamp, standard lamp, television, video, computer, mixer, blender, fridge, freezer, power drill, jig saw, soldering iron.

## How many watts is 3 amps?

## Can I replace a fuse with a lower amp?

Do not use a fuse with a lower rating– don’t put a 20 amp fues in a 30 amp circuit–because it probably will blow prematurely. Conversely replacing a 20-amp fuse with one rated at 30 amps is dangerous because it may not blow soon enough and damage an electrical component or start a wiring fire.

## How many watts can a 20 amp fuse handle?

For standard 120-volt service, a 20-amp breaker can support up to 2,400 watts on a single circuit. However, circuits should not be loaded to greater than 80 percent of their maximum capacity for long periods, which makes 1,920 watts the safe maximum for a 20-amp circuit.

## How many amps is 600 watts?

## Can I put a 10amp fuse in a 5 amp?

Possibly yes. What ever is wired into that 5 amp slot is rated for a max of 5 amps, overdrawing more than 5 amps by removing the 5 amp fuse and putting in a 10 amp fuse can possibly short out a circuit.

## How much current can a 13 amp fuse take?

BS 1362 Fuse Operation Characteristics In fact a 13A fuse will allow a current of 20A to pass indefinitely without blowing.

## How do I convert watts into amps?

Amps calculation with line to line voltageI(A) = P(W) / (√3 × PF × VL-L(V) ) So amps are equal to watts divided by square root of 3 times power factor times volts.amps = watts / (√3 × PF × volts) or.A = W / (√3 × PF × V) Example. … I = 330W / (√3 × 0.8 × 110V) = 2.165A. Amps calculation with line to neutral voltage.

## How many watts can a 15 amp car fuse handle?

1,800 wattsThe circuit and circuit breaker that you tripped have a capacity of 15 amps, or 1,800 watts (15 amps x 120 volts = 1,800 watts). The lights drew 360 watts, or a measly 3 amps (360 watts divided by 120 volts = 3 amps)—well within the capacity of your 15-amp system.

## Can I replace a 5amp fuse with a 3 amp?

If so, yes, you can replace a 3A fuse with a 5A fuse. But consider this. A 3A fuse was used for a reason. If you replace it with a 5A fuse you will lose part of the protection the 3A fuse was intended to provide.

## How many watts can a 10 amp fuse handle?

1200 Watts10 Amps x 120 Volts = 1200 Watts.

## How do I know what amp fuse to use?

Formula to Calculate the Fuse Rating V for voltage in volt); I for current in Amps. The fuse rating can be calculated by dividing the power used by the appliance by the voltage going into the appliance. I (Amps) = P (Watts) ÷ V (Voltage).
