    hi all,

    I got a 10A three phase machine and got a 10A three phase socket at the wall. That's not a problem when connecting it just like that to the power. My problem is that i got a 20 amp leakage tester, the 10A three phase machine plug goes in to the input of the leakage tester but the 20A output which needs to go into the 10A three phase socket at the wall doesnt go in. Knowing that the machine does run 10A is it possible to create a 20A to 10A three phase extension lead that can be used between the output of the leakage tester and the wall socket? Also what would happen to the neutral pin in the 20A in the extension lead as a 20A plug has one and a 10A doesnt have one.

    I would think a good electrical distributor would have 4 conductor plugs and sockets as well as 4 conductor SO or SJ cord for making your own extension cord. I haven't checked, but it is possible LOWES or HOMEDEPOT may have the components to make it.
