How is short circuit protected?
A short-circuit condition means a circuit allows the current to flow through an unintended path with very low electrical impedance. It is a direct contact between two points of different electric potential.
How do you know what size fuse to use?
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.
What size fuse is needed for a 1000 watt amp?
80a
Can you use 5 amp fuse instead 3?
No. The current rating of a fuse means the fuse will open when the rating is hit. Fuses protect the equipment being used as well as the power side of the circuit. If you need to use something NOW and the fuse is a 3 Amp slow blow you could use a 5 Amp fast blow without much worry.
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.
Can you put a 3 amp fuse in a 13amp plug?
Yes of course there is. The cable or flex attached to the gas fire is purely to supply the ignition. The flex provided is not rated to 13A because the ignition requires very little current and so the flex requires protection by a 3A fuse.
Can I use 13A fuse for 3A?
IET Forums – 13A fuse in 3A plug. yes – but we are only protecting against a dead short at the applience, not normally some mild overload – a dead short takes out any fuse or none, overload is managed at the appliance end of the cable – which is the EU wide approach with non-fused plugs.
Is it bad to use a higher amp fuse?
Do not replace a blown fuse with one that has a higher amperage rating. The fuse has a specific amperage rating because it is intended to be the weak link in the circuit to protect the electrical components. A blown fuse indicates excessive current has entered the circuit.
Is it OK to use a 13amp fuse instead of a 10 amp?
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 is a 1 amp fuse used for?
1 AMP Ceramic Fuse are suitable for various different uses. These include providing a reliable performance and cost-effective circuit protection. They are ideal for use in plugs to protect cables from melting or catching fire if they are overloaded.
What amp fuse do I need for a cooker?
13 amp fuse
