Black and White power lead cable wires

[RobbieGong]

I'm replacing the two pin plug from an amp to three pin.

There are two wires only one black and one white

Which one is positive ie: equivalent to usual red / brown live fitted to right and which is negative ?

[struth]

kinda depends. is either wire connected to a chassis point

I assume you are talking about the mains lead.
As it is only two wire it is probably a double insulated unit so it really doesn't matter which is live or neutral.

With a 3 wire connection including a green/yellow as the earth conductor, the black would be live and the white neutral. Common on the continent.

Hi yes it's the mains lead out of an amp.
I cut off the two pin to fit three pin and revealed two wires inside the mains lead, one black one white

[RobbieGong]

Also the power cable from the amp has a solid white line down one side. This is the side that the white wire runs along.

I dont want to fit the the UK three pin and get it wrong if ie: does the white or black go to the left or right when I fit the plug ? ?

Is the item of US origin? The US colour code for mains cables is:

Black - live (and hence will go to the right (fused) terminal of a UK 13A plug)

White - neutral (and will go to the left terminal).

Hi Barry,

Japanese amp, but I was guessing same as you, ie: Black to the right and the White to the left but just a guess

Fitted the plug to this configuration last night Barry and happy to report, nothing blown up, no sparks, no flames :eek: :)
