Volt drop is not only about whether something will work or not, it's about the current increase in the system when it happens. This can damage compressors in fridges, overload cabling you've only got to drop down to 200 volts and a 3kW fan will draw 15amps and although it will still work, it's far from ideal.

But won't a 3kW motor rated at 230V draw less current at 200V, and consume considerably less than 3kW?
If you have a load rated at 3kW at 240V, by what magic will its impedance decline from 19.2 ohms to 13.33 ohms if you reduce the supply voltage to 200V?Pensdown said:

Um, not sure what you're referring to, but you certainly caused me to question my understanding of V=IR when you implied that the current in a circuit is in inverse proportion to the voltage applied to that circuit.Pensdown said:
