Safe Isolation and switching!

[leighman]

I inspected the circuit and then switched it back on. I then switched it back off to test it. I now realize I should of tested the circuit before switching it back on. But even Not testing before switching back on would not of caused current using equipment to fail and the tests themselves could not of highlighted the potential to do so.

Let me clarify what I just said: I think I confused the reply: I completed the installation and then switched it back on before testing it - which was wrong!

I then isolated the final circuits again so that I could perform the necessary tests.

Sorry leighman, could you give us more details of the tests you carried out.

Ok,
So how do they suggest that your testing on the 240V AC side caused a problem on the LOAD side of their power supply? I presume you were testing at 500V DC with a standard megger or MFT?
