[QUOTE="sirsparkabit, post: 490539, member: 175"] Hi All, Is there anyone who deals with refrigeration in the forum who could possibly help me with cable sizing ?. We have 2 freezer units on trailers at work which are currently running off of 2 13 amp sockets with commando plug to 13 amp plug adaptors . Cable length is around 5 metres going to each and they run fine on this circuit and have for some time. Work want to move them and run a swa cable around 55 metres and put them on there own mcb . Plate details are Minimum current 7 amp s Maximum current 12 amps Start up current 40 amps Monobloc refrigeration unit . I don't have a lot to do with motors and compressors so am I sizing the cable based on start up current which seems odd to me , however I would like to understand this if anyone can put me right I would be most grateful. Regards . [/QUOTE]
