High Zs on auxiliary circuits Discussion ThreadHigh Zs on auxiliary circuits Electrical Advice
Hi
I have a distribution board controlling conveyor belt in which all auxiliary circuits for start/stop switches, emergency buttons, etc are supplied through 230V/230V separating transformer.where secondary winding is earthed on one end. I've got high Zs readings for all those control circuits (~20Ohms) protected by 2Amp circuit breakers
It's 230V so low voltage fixed installation requiring inspection and testing with 0.4s disconnection time (TNC-S). Can't find anything in the regs how to treat this situation. Would it be departure due to DB manufacturer design?
