Type AC RCD's and EICR's

[UNG]

I think it's a useful tool to help you think through the inspection and prompt you as to things to look for and consider. My point was to get thoughts on the suggestion that pretty much all type AC rcds you come across are a C2, or how do we go about making a judgement as to whether there are likely to be pulsating dc currents present

The problem is a one size fits all approach doesn't always work and the it must be right cos it says so in codebreakers does not absolve the person doing the EICR from making the correct decision, the most useful tool is actually BS7671 and not some book that carries the opinions of those who have not seen the exact scenario and circumstances you are working with. If you speak to people who contributed to codebreakers they don't necessarily agree with all the outcomes listed so it is clearly flawed
