[ICOM] PW-1 220 VAC US wiring?

[Adam Farson]

Hi Kent,

All understood now. I had the same situation at my former home in Boca
Raton, FL. The clothes-dryer had a 4-wire, 120/240V plug.

Inside the socket you will find black, white, red and green wires. The red
and black wires are live, the white neutral and the green earth (ground).
The dryer needs 120V for its timer and control circuits so uses the neutral.

Red to black is 240V.

Red or black to white is 120V.

To be sure, measure the voltage across the red and black conductors. If it
is 220 to 240V, connect your PW1 across these. I would actually recommend
that you bridge a 220/240V 20A receptacle across the red and black leads of
the dryer socket via a 2-pole 20A circuit-breaker, or make up an extension
cord with a dryer plug at one end, the breaker in-line and the 3-pin
220/240V 20A receptacle at the other.  Connect the green (earth) wire to the
earth pin of the new receptacle (for the PW1), but disregard the white
(neutral). 

This is probably in breach of the electrical code, so be careful.

Hope this is helpful.

Cheers for now, 73,
Adam VA7OJ/AB4OJ

Thank you Adam.

I guess I am not making myself very clear.

My Dryer HAD a 3-wire plug on it. I moved, and the new house has a 4-wire
socket. So, I had to rewire the Dryer with a 4-wire plug. The instructions
were in the Dryer owners manual.

My PW-1 HAS a 3-wire plug on it, that was used in VA on 200-240vac.

The instructions on p. 5 of the PW-1 user manual is fine for "3-wire"
connections. If I have to plug it into a 4-wire socket, how do I do that?

And I don't want to connect it to 120vac, and only get 500 watts out.

If an electric dryer manual can tell me how to hook it to 4-wire, then ICOM
or this forum should be able to tell me about my PW-1 too<g>.

Thanks
Kent

The instructions for connecting the IC-PW1 to various mains supplies are on
p. 5 of the user manual.

The IC-PW1 does not require a 120V supply hen connected to 220V mains.
