Hi there,
I have a number of 22kw heater sunning of 3 phase supply. There is a dial with 4 settings 1 being the lowest output 4 the highest.
The problem I have is when ever it is set to maximum output it is knocking out the breakers not discriminating at the rcd but knocking out the main breaker as we'll. When I have opened the unit 1 pf the connections to one of the heating elements has burnt out. It has happened to a couple of other units too.
Could it be it do with the system not being adequately balanced?
Any help would be greatly appreciated.
