[QUOTE="myksterx, post: 503030, member: 32956"] Hi, this is my second post here please do not bite. I had fantastic responses from previous post that put me right and everything has been fantastic since. Thank you again. i have a 2.5mm ring on a 32a breaker going into my shed and into my man cave (both joined onto each other) had no issues at all. until recently i have added a brand new wall mounted air conditioning unit, which was installed professionally mind. it all works well and good, but since installing this unit, my electric trips on the 32a breaker every other day, even though the air conditioning unit is continuously in use. i have had the installer out. He has tested all his work, all wires, tested the actual unit. Which is brand new. All is well there. i done a test and turned the aircon off for 7 days. No random tripping. then i done a test and kept aircon on for 2 days, random trip. then again a few hours after with aircon on. i then switched the aircon off and again, trips stopped. its 100% the amount of power being dragged through on this ring and its the aircon unit sending it slightly over the edge. my question is. can i safely add a slightly bigger amp fuse? i am currently on a 32a fuse. what would be the next jump? 40a? Or less? would that be safe on the actual 2.5mm ring [/QUOTE]
