Best kept secret in AC line filtering conditioning

... maybe 230V as opposed to 110V has something to do with it? I don’t know, apart from 230V equipment drawing roughly 50% the current of 110V.

You're confused. For any given load, the current will be the same as 120VAC as it is at 240VAC. See Laws of Thermodynamics, conservation of energy.

@cleeds
1000Watts @ 240V - 1000/240 = 4.16 Amps
1000Watts @ 110V - 1000/110 = 9.09 Amps
My point being if connections are not perfect trying to pass 9.09 Amps through them will cause more problems than passing 4.16 Amps.

You’re confused, and now you’re comparing apples with oranges.

@chris_w_uk. Sorry, but you just don’t know what you’re talking about. The component will draw the same current at 120VAC as it does at 240VAC. If the component draws 1,000 watts at 120VAC, it will draw half that wattage at 240VAC. You’re confusing voltage with current.

@hilde45,

That would be assuming the identical piece of equipment being used at 110V and 240V, whereas the equipment would be built for the particular voltage being used, so both pieces of equipment would be different so they produce the same Wattage output. If an amplifier manufacturer builds a 100Watt amplifier and sells it in the UK and US they fit the appropriate power supply to feed the amp with what it needs to produce 100 Watts. They don't sell it with the same power supply in both countries as 100 Watt in one and 50 Watt in the other.
