    No problem, could try a petrol/diesel generator some do 110v / 240v but don't always put out an earth which could be a problem.

    or you could get someone to ......

    the earth problem can be overcome with an earth rod and a straper (as most gennys had a earth point on them normaly a screw on the case)

    Any big site I know would throw you off site for transforming 110V to 230V (and rightly so, as it defeats the whole object of having 110V site supplies).

    That said, my PAT tester can be operated from either a 110V or 230V supply so they certainly exist.

    Would a battery-powered PAT tester be more suitable, particularly if you are considering a 110v one?

    Seaward do a range of battery-powered units.

    I know you didn't. But introducing 230V into a site requiring 110V is a nonsense.

    not if you need to power a tester that can only be supplied by 240volts and can not warrent the cost of a 2nd pat for 110v supply just saying is all like i said may just end up with a 110v only pat (for uk use with uk spec) for just this need

    Then possibly you are not the correct person for the job?
    Sites are 110v for good reason you are asking a lot of the contractor to take responsibility for you going against the norm.

    I'm also a bit surprised they are asking you to 'wander' around the site looking for items to test. How do you know you have got them all and something has not been moved into an area you have already passed through.

    I have to agree with Risteard, what you are proposing is not the best solution.

    Dragging round a transformer all day, that may not be permitted on site, is a pain the in the backside. Particularly in the case of PAT, you've got to pick it up and move it every ten minutes.

    You mentioned you might get a new tester, so why not a battery one?
    It would be easy to carry round, you wouldn't have to worry about a power source and you'll be quicker doing the job.

    Even our hosts stock them:

    How would you do load tests on 110 tools with a 240 source?

    via a pat that has a buit in step down transformer (there is a handful of pat that can only use a 240v supply but have a built in 110v socket and a 110v stepdown transformer)

    It would be a heavy PAT tester with an inbuilt transformer. My PAT tester can be powered from either a 110V or 230V supply. To do load tests etc. on equipment it must be powered at the voltage of the equipment you are testing.

    yea it was a heavy pat tester i had used (was on loan to me at the time) and was a brute to use

    I'm sorry to say this but I really question your ability to do this safely. Your looking to step up the voltage to 240 to have a pat machine that I suspect is very unusual step down to 110?

    I doubt if any would step down with the capability to do load tests. It makes no sense that someone would want to carry that about with them

    Will be fun lugging that around a site...

    well this old tester i was loaned did have a buit in 110v step down transformer any i buy wont be used like this 1st im getting a good 240volt pat then if i get a site contract then i shall buy a 110 volt (uk spec) pat for all my site testing needs simple

    Apologies the Seaward Supernova does dual voltage run tests, but it's £1300. Much better to buy a 110v unit and save money and weight if you want to do it properly

    yea it was fun lugging it round it nearly fell out portable equiptment type due to weight
