Hi, I'm training to become fully qualified so know very little at the moment (just a domestic installer right now). I looked at my electrics and can see two lighting circuits not on either of my RCD's. I know this is not safe and wonder why, if I have two RCD's, are the lighting circuits not on them and also can I just add them to the busbar on each of the RCD's?

    I`ve installed hundreds of circuits without RCDs and still going strong.

    They are a relatively new idea.

    Although they can and often do make the circuit much safer.

    You`d need to test your circuits first for insulation resistance and borrowed neutrals (& the ither tests too).

    If all`s well and you consumer unit is modern enough then you might be able to use RCBOs for the two circuits thereby giving more resiliance.
