Do we use the correct type of RCD's for our installations ?

[Jimmy Boy]

Just as a matter for friendly discussion, I think most of the sparks on here know which B or C type breaker etc to use for a particular application, but do we give any thought to the possible different types of RCD's there may be and their applications ? Setting aside time delay which is common, if you picked up (Say) an MK RCD would you be able to tell by looking at the symbol on the front if it was a type AC, type A or a type B ? and more importantly would you apply some thought to their design use and the installation you are about to fit it to ?

Play nicely...

Er...no.....unless it's going to be time delayed I grab one from the shelf at city's...fit it....test it...and clutter off home.
For those not sure here's an explanation.

Well it might interest you to know that MK RCBO's are A rated so AC+Pulsating DC where the most common RCD off the shelf ( Setting aside delayed ) would be type AC denoted by the single waveform, might be worth having a read up if your doing installs with a lot IT gear in it.
