took measurements whether the water boiled faster if the cooker was on a 25 Amp circuit instead of the required 16 Amps.
That reminds me of the guy here who wanted to know if connecting a 3kW heater to the lighting circuit would make it cheaper to run. He figured that running from a 5A circuit would make it use less power than when plugged into a 30A ring.
I guess he was right in a way...... As soon as the 5A lighting fuse blew it would cost absolutely nothing!
