Portable power tools in Factory

[Conners1274]

Please could you let me know wheather or not it is illegal to use 240V portable power tools on the shop floor of a factory.

Conners1274,
That is not an engineering question, that is a policy or safety code question. The only people that can answer that question will be those in charge of YOUR plant's policies and safety codes.

Since standard power in the UK is 230 V, I would assume that all portable appliances would operate on 230 v.

I know of no law in the US that prohibits using 220 V power tools. In practice, 220 V outlets tend to be dedicated. Almost all convenience outlets are 120 V.

See

and the HSE website for UK work. You should always specify your locality for local questions on an international forum.

Good Luck

Ah yes.

Hiya-

Air tools from China are getting really cheap here in the
U.S. They tend to last quite a while, are sturdy and
reasonably well built. They do not have the electrical
safety issues, needless to say.

Many folks have used air tools for years in manufacturing.

They have the added advantage of not wandering away from
the factory floor as often!

Cheers,

Rich S.

It's also nice when the tool gets cooler in your hand the more you use it rather than warmer.

...until it gets so cold you can't hold on!

Although the UK LV supply is 240/415V, most industrial tools are designed to run on 110V and are supplied from an isolation transformer with a centre-tapped 55-0-55 winding. The centre tap is grounded, and the most severe shock potential to the user is therefore 55V to ground rather than the 240V he would be exposed to if using a tool supplied directly from the LV distribution system. Higher risk applications use 24V AC, typically for lighting.

I am not a fan of air tools for drilling and some grinding operations. An electric moter will rise to the occasion due to its torque curve where a air driven tool will fall flat on it's face. At my company we use a few air driven drill motors and I see them failing to complete the hole (task). I will give you this, it is a ill designed and maintained system. But a Millwalkie Power drill will punch the hole everytime (IMHO).
