Can i use a 240v without a transformer and instead get a lead to plug direct to mains?

Steven2521 · 8 November 2018 at 11:51PM

Recently purchased a Makita core drill but didn't realise(because at the time I hadn't worked in this environment) that it had the yellow adaptor instead of a3pin plug. Im hoping that I can just get a connector to change to a 3pin (like one you would use on a caravan) and plug directly into the mains?
Is this safe?

Thanks for the help 👍

You need a 110 box

110V Makita core drill going cheep anyone

ceredigion:

What makes you assume that? Are you saying I can't plug a 240v straight to mains at 240v? Not being facetious, would just like it divulging.

if it's a yellow plug it will be a 110 volt drill for use on building sites, and must be used through a site transformer.

If you connect it directly to 240 volt mains it will die.

You need something like this.

But, not only is it nearly £70, it says the weight is 17 Kgs. That's a fair extra weight to lug around.

Before doing anything else check the rating plate on the drill. What voltage does it say on there?

If you purchased it recently and haven't used it you might be able to take it back and swap it for a 230v one if necessary.

You will start a fire connecting a Reduced Low Voltage drill to a 230V supply. It is designed for a 110V centre-tap Earthed supply (with 110V between phases and no neutral).

It certainly won't be good for the drill! It's a bit alarmist to say it will definitely start a fire.

It's more likely the control circuitry will burn out and emit the magic smoke. Or the motor coil will overheat and one of the copper strands will snap or burn out.

As this is a good quality drill, there may even be a thermal cutout that saves the drill from serious damage.

I am not convinced the OP should be allowed access to power tools at all.

The drill's rating plate is the definitive place for this question to be answered. If it is rated 110v, or a 110v-based range (e.g. 110v-120v) then it cannot (and must not) be used on 240v mains.
