Question on making my own electrical plug extension?

No I mentioned in first post it is 16amp, generally 1.5mm2 is 15 or 16amp.

As for the point about using the 0.75mm2 wire which is 6amp, I think it is clear now, for the purposes of making an extension use the 1.5mm2 whatever electrical product you intend to use the extension for especially if you intend to use it for a washing machine.

Apologies, misread it.

peeps generally have no idea of what some electrical items use in terms of power.
ie
the washing machine at 2kw, a kettle at 1.8kw, a lamp bulb at 60 watts.
and yet a typical fridge uses only 35 watts!

Seems as though generating heat through electricity takes a lot of power, light not so much.

Bit suprised by the fridge doesn't the fridge generate heat as well, or is that just the heat transferred from the fluid that it just pumps around-in which case it is a case of electricity for movement.

So regarding power usage when electricity is used for
Heat - Very High
Light - Low
Movement - Low
is that correct?

Surely it's not good practice to run a high power device like a washing machine (as ormus says, can be 2KW or more on the heating cycle) permanently off a plug socket, let alone off a plug socket and then an extension lead?

Why? They come with plugs and are designed to be plugged into a socket.

Much better to fit and use an FCU near to the device.

Some people believe you have to be trained and qualified to fit a plug, don't blame me when they come in here and tell you that you have to have served an apprenticeship before you can fit an FCU. :rotfl:

ormus

a qualified yes.
domestic lights rarely are above 500 watts. ie outside security lights.
any heating uses a lot of power.

movement? be careful here.
little motors use little power. a 1 hp motor is nominally rated at 746 watts.
so you can see the fridge motor is very small.

its not often you will see a large motor in domestic useage.

A bit of common sense from geordie joe

WE need to teach kids these days to be a bit more useful
and starting with 'playing ' with plugs



Where will it end ...... calling in a 'sparks' to change a light bulb???

It won't end there, he may have to bring 3 mates to help him! :eek:

The BS1363 plug was designed and rated to safely carry upto 13A (2990W at 230V) and the design has been proven over the last 50 years. What makes you think it is unsafe when used within its' rating?

macman

I was referring more to the use of an extension lead, which introduces another plug into the route. And an FCU avoids the possibility of wet hands on a plug and socket.
It didn't say it was inherently unsafe, I used the phrase 'good practice'.

ormus

the BS 1363, 13 amp fused plug was designed to protect the appliance & the circuit. not the user!
a normal fuse takes time to blow.

240v can kill the user long before the user blows any fuse.

And entertaining when you learn that a 1362 fuse will carry twice its rated current for 30mins at least
