As some might have read we've been supplied with a number of oil filled radaitors

So I unpacked them and installed them, one by one.
In an attempted to trip our 32 amp circuit braker I would have thought that 5 would have done it, but they didn't.
On switch on they started at about 1.6KW (using an old maplin power meter)
I left them fully on, that's the highest setting .
The lab voltage dropped from the 220V to about 202V so that accounts for it I guess.
But what realy suprised me was the power consumption of a radiator when it was full on, anyone care to guess what it was.
Voltage 202
Is that a B32 MCB? If so, it will trip according to the "B" trip
curve, which means that instantanious trip needs at least 3 x rated
current.
At 220v, 5 x 1.6Kw heaters will draw at most about 36A, which will
essentially never trip a B32 MCB.
See the trip curves he
