    Hi,

    What fuse should be in a standard 3-pin plug. I want to buy some and I just looked at 2 of my existing ones and one (kettle) is 13amp and the other (table lamp) is 3 amp.

    Is there a general rule?

    One of the plugs will be for a mini guitar amplifier, and the other will be for a small TV.

    It depends on what it is connected to. As a general rule, if something creating heat is connected, like a kettle, a heater, hairdryer, then "the load" will be high. Accordingly 13Amp is required.


    If it is a lighter load, then 3 Amp fuse is required. what are you planning on connecting it to? Does it say what the power of it is?

    Don't they already have plug tops fitted?

    At a guess I expect the 3A fuse would be okay for both the amp and the tv, but obviously I don't have specs for either.

    "The following points offer a general ‘rule of thumb’:

    A 3A fuse is the safest type of fuse to use, as that gives the greatest level of safety; it only takes the current to surpass 3 amps before the fuse blows
    In older appliances different types of fuses, such as 5A, 7A and 10A, may be found. If the appliance has a rating less than 700W, then these fuses should be replaced by a 3A fuse. A 5A fuse is safe for appliances rated less than 1,200W"

    The standard plug comes with a 13A fuse. When buying the plugs buy a packet of mixed fuses.
    Then follow advice in the previous post.
