[ARC5] BIG Variacs and popping breakers.

[Brian]

Hello John,

For a cooling fan rated at 110 Vac but running off 230 Vac, I put a 0.5 uF capacitor in series. I can’t really give you a definite capacitor value for radios – which radios, what power consumption, what Voltage drop? Easy to arrive at with my little capacitor box and a Voltmeter across the powered item.

The right types can also  be found in an old microwave power supply ( with 50-60hz supply).
I think they were in the 1 uf range .

What values do you use a lot for the radios?
