Can i change the plug socket over from 110v to 240v supply on my HR2470T-1/1
It would not be OSHA approved if in the US in an industrial location.
While not recomended practice, it can be done in the US to run off of 4 wire 240. You are just connecting to one half of the 240 outlet.
If you are in the UK or elsewhere with 240/250 volt mains- do not do this, use a voltage reducing transformer instead..
In the US, the standard is 120 /240 Or put another way- a 240 volt circuit in the home in the US, has 2 120 volt branches that share a common return, the 240 is derived across the 2 "120 sources"- hence your 2 pole breakers on 240 volt branches. If the socket is 3 terminal- which was old code- ground and the return were common at the outlet, it is a matter of just making sure the 240 volt plug terminals the 120 volt drill gets attached to is the ground/return (the one with the nib on it to make it index correctly in the outlet- (should be the wide blade lead or white and one black in the drill goes to either"hot" side of the plug- either one will work, and only one. On a 4 wire outlet, which is new code- the return goes to the white wire of the drill. And the black goes to either one of the hot sides. If drill has conductive case and grounding wire- that should connect to the outlet ground.
Mark on plug which two blades are used, so if you take it somewhere else, you can check (which should be standard operating procedure) with a meter to make sure their outlet is wired correctly.
