[QUOTE="monkey5, post: 72920, member: 1819"] hi, first of all ill like to say thanks to this forum as i have learnt a hell of a lot by some of the posts. my first question is on a niceic form under "maximum Zs permitted by bs7671" would you write the figure from the red book or the tabulated based on 80% of values ie for a 32a type b would you write 1.44ohms or 1.15ohms next question what the best way to do a rcd test an rcbo on a light circuit, as testing at lighting point will expose live parts. and finally if changing an unprotected mcb to an rcbo of same rating (say for a lighting circuit) would this be classed as a minor works? thanks in advance wayne [/QUOTE]
