[QUOTE="Hanky123, post: 387779, member: 25904"] I did a test on a 6way 3phase db yesterday and the highest reading of all 3 phases was 3.2ka which I doubled to create 6.4ka, (the recorded reading). Some of the single phase mcbs are only rated to 6ka so should I upgrade them to 10ka or is it ok as they are only using one phase? Thanks in advance. [/QUOTE]
