[Elecraft] KPA1500 AC Mains wire colours

[Peter Hall]

You’re welcome, Doug.  I’m glad you have the KPA1500 up and running.

Your note, and my recollection of installing my own KPA1500, identify an important omission in the KPA1500 manual.  Some other shortcomings of the manual (such as a decent working block diagram) are merely irritating but not including the proper mains connection for a $5000  device shipped internationally is a serious oversight.  It’s clear there is not a widespread appreciation of global power standards in this email group (for example) and, rather than having a future user stumble across incorrect or incomplete information, the Elecraft manual needs to have the definitive instructions up-front.

I’m not sure how the EU regulations are constructed but I suspect that it’s technically illegal to use the supplied cable in Australia.  For Australian users a more immediate consideration on opening the box is that the US cable won’t fit through a standard Australian mains plug cover.  You can buy one Clipsal brand plug from a specialised electrical wholesaler which will work, or you can use a heavy duty plug and socket if available.

73, Peter.

Ken, Doug

Ken is correct.  Your amplifier comes with a US colour coded cable and, for your 230V supply, black is active, white is neutral and green is earth.

I had some additional searching to find an Australian heavy duty plug that would fit the supplied mains cable and a standard 240V outlet, but was in the end successful.

Regards,
Peter, VK6HP

Doug,I don't have a KPA1500 but these are the standard power cord wire colors and functions:

*Function   USA      Europe*
Neutral       White    Blue
Hot             Black     Brown
Ground       Green   Green/Yellow stripe

If there is any doubt you can send an email to Elecraft; they are very responsive and helpful.
