What amp fuse should be in a plug?

Plugs for appliances rated between about 700 watts and 3000 watts (the maximum rating of a wall socket) should be fitted with a 13-amp fuse (coloured brown). For example: 13A Fuse – Washing machine, dishwasher, microwave, kettle, toaster, iron.

How do I know which fuse to use in my plug?

The simple calculation is watts divided by volts equals amps. After you have calculated this, it is a simple case of adding around 10\% to the value and choosing the nearest fuse to match. This is a more precise method then just guessing should you require a 3, 5, or even 13 amp fuse.

How do I choose a power supply fuse?

A fuse should be de-rated by 25\% at room temperature, meaning if there is a 7.5 amp circuit, a 10 amp fuse should be used at 25˚C. Voltage ratings on a fuse can be higher than the voltage on the circuit, but not lower. At the end of the day, a simple fuse is a great way to effectively protect a circuit.

What size amp fuse do I need?

The correct size of fuse to use depends on the amp you are wiring. If your amp has an internal fuse, then your inline car amp fuse should be a bit larger. For instance, if your amp has an internal 20 amp fuse, then you should go for a 25 or 30 amp inline fuse.

How do I know what size fuse to use?

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 are the standard fuse sizes?

Generally, two sizes of user-replaceable fuses are found: the 1/4” x 1-1/4” and 5×20 mm. Each is available in a variety of volt and amp ratings. There are two basic types of fuses available for appliances and consumer electronics: fast-acting or time-delay.

What does a fuse do in a plug?

The fuse breaks the circuit if a fault in an appliance causes too much current to flow. This protects the wiring and the appliance if something goes wrong. The fuse contains a piece of wire that melts easily. If the current going through the fuse is too great, the wire heats up until it melts and breaks the circuit.

What type of fuses should I use?

Fuses are power dissipaters that destruct when enough voltage and current are applied to melt the wire. There may be a conversion table available from a manufacturer, but with the price of fuses that small being so low, I’d be surprised to find much information on the subject. If your application calls for 24V D, 2A rated fuses, just use them.

What size wire do I need for a 24V power supply?

For the Neutral, Live and earth ground, wire gauge for that level of current is 14 for relatively short cable lengths. Increase the gauge for longer lengths past 25 feet. For the DC 24V output terminals to the drivers, 20 gauge is fine. If the power supply is connecting to only one driver, increase the wire gauge to 14.

Can I use a 13 amp fuse on a 60 Hz plug?

However a 13 amp fuse would be fitted as standard into the plug by the manufacturer, any fuse lower than even the 10 amp would fail. If the appliance shows 60 Hz, then this appliance is not suitable for use within the UK. If the appliance shows 50–60 Hz it is suitable for the dual use (Europe/UK).

What size fuse do I need for a mains plug?

A mains plug takes a 25.4 mm (1.25 inch) BS 1362 fuse, these fuses are available from any local supermarket or DIY store. They are cheap so don’t risk stealing a fuse from another appliance just to get your appliance going, unless you are using a fuse of the same rating. “I have a pre-fitted moulded plug on my appliance and there is no fuse?
