[Amps] Power cord to use when converting AL-80B to 240 volts?

[Will Matney]

Mike,

That was one of the reasons I used them plus they were cheaper than going and buying a piece of SO cord and a plug. They make some smaller for large window air conditioners running on 220 Vac too. However, I just went and looked at my dryer cord and it couldn't be over 14 gage, maybe 12 at the most as it's only about 1" wide if that. One of those same flat grey cables. It did use a 3/4" conduit clamp instead of a 1/2" though. If I recall, most range cords are smaller than a dryer cord, and the circuit doesn't require as large of a breaker, I may be wrong. I imagine why the cords are as cheap as they are is where their mass produced. You can find them cheaper at the surplus houses like H&R. I bought mine at a supplier who specializes in HVAC, and appliance parts named M&R Supply in Huntington, WV. Of course I had a discount there at the time where I was a business. Lowes and Home Depot has them about as cheap.

On AM/SSB amps, it takes more as not only do you have those power peaks but you have a carrier that has to be supported. Most amps are made for both so you have to size everything around that usage unless you'll never operate it on AM.

Best,

Will
