Hi ,
Currently doing a design project in college and I need to pick a circuit breaker ( In device rating and type) for a food holding equipment unit that requires a 16A 400V three phase and neutral supply that is supplied by 5 core SWA. I think I should pick a 16A 3P+N RCBO but wasn't completely sure so thought I would run it by on here 1st before I write anything down.
 
You will need to now if there is start up current on the equipment. To choose what type of mcb / rcbo B C or D .Also Just wondering if 16amp ocpd is a bit close to the limit if the equipment demand load is also 16amps.
