9inch 110V Grinder plug question?

my3cents · 25-09-2014 05:59PM #1

I've just bought myself a new 9inch 110V grinder. Not for commercial use only home use but as it will get used outside in a damp shed and I have other 110V gear including a couple of transformers (3.3KV) I thought I'd get the 110V version.

So got it home and there's no plug on it. Now without saying any more I want to know how many electricians have a similar sized grinder and what rating plug is on it?

The reason for the question should soon become evident

Go to nearest electric wholesale and ask for a yellow 110v plug.

Good answer, same answer I would have given but there's a catch and I want to see what the general practice is.

The tool shop where I bought the grinder also gave the same answer.

You're supposed to use these type for colour codes and safety.
110v=yellow
240v=blue
380v= red.

You really don't want to make the mistake of pluging a 110v item into 380v

Its the only 'right' answer.

You could follow it to the letter and fit a 32A plug, but I would bet the vast majority of all 110v 9" grinders have a 16A plug fitted.

That's what I wanted to hear

I suspected as much, grinder is rated at 19A and I wondered if a lot had 16A plugs fitted.

Yes, every 110V grinder that I have seen has a 16A plug fitted.

A 32A plug will cause more issues than it will solve

shiny new makita ?

~ 2000watts n a little bit = more than 16 amps

those little yellow plugs n cables are only rated to 16 amps

you need the bigger ones - rated to 32

No just a cheap Hitachi but a very expensive diamond cutting disk.

The 32A plug is easy but then I need a site transformer with a 32A socket because the "common" two plug 3.3KVA 110V site transformers while just capable of the load only have 16A sockets.

I could of course buy a 5KVA transformer with 32A socket but they are €250 compared to €75 for "common" 3.3kV one. The 5KVA tansformers are also very heavy to move around (30kg or thereabouts).

Considering I only use a grinder for short periods outside and I am aware there is a possible problem I'll use a 16A plug and see how it goes. The cable isn't an issue as I won't be using it with a 110V extension.
