    Ferrule for triple solid core CPC in socket w/metal back box

    Ancillary to my other post, I wanted to check if something was up to standard in part of the installation I'm doing. We have a metal back box in this case. I've got a fly lead going to the face plate, which has the two other CPC cables going to it also. I've not been happy with how sturdy the...

    Additional sockets on stud wall.

    I will soon be adding some (2 or 3) additional sockets to an existing timber stud and plasterboard partition wall, and had some questions about mounting the back boxes: Can a metal back box be “side-mounted” to a timber stud? Ie, drill holes through the side wall of the back box instead of...

    I'm trying to fit dimmer switches but there there isn't enough space in the back boxes. I have replaced some of the boxes with deeper units and cut down wires but there still isn't enough space. Any ideas?

    Back box spacers or links

    I know I’ve seen them before…. But I can’t think of a name. I’m needing a line of metal back boxes in a kitchen… 2 lots of 2x 2 gang and a 1 gang. I just want them to look evenly spaced. I could do it with a couple of brass bushes and a steel conduit coupling, but I’m sure I’ve seen a plastic...

    Why are single gang boxes still made with 4 fixing lugs?

    Hi all, I am an experienced DIY electrician and I just wanted to ask a quick question about something since I am new to this forum, if it hasn’t really been answered anywhere else. The question I have in mind is how come most electrical manufacturers still make single gang (25, 35mm etc) back...

    EICR - Shallow Back Box Depth a Fault?

    Hello, My house has 25mm back boxes throughout, but I’ve noticed the previous owner has installed sockets and switches that seem to suggest/specify 35mm minimum. The sockets and switches do still fit flush on the wall, just that it is incredibly tight behind so the wiring has been routed...

    How to fit a metallic back box on a stud wall?

    Hey everyone, I'm trying to understand how to fit a metallic back box on a stud wall. Should it be fixed to a stud (on one of the sides) or is it expected to be fixed to a noggin? In either case, how would I know exactly where a noggin or a stud is, so that the hole I cut on the plasterboard...

    Back Box In Hollow Wall Installation

    Hi Guys, I've completed rewires with hollow walls before and was able to use a dry line Box. No chance of being able to use them this time. I've never seen walls like this though. Just wondering how people have installed back boxes in this circumstance? I've attached a pic I'm assuming...

    Passing another circuit through back box

    Had a bit of a ‘discussion’ today with another electrician. Basically found a light switch in which the radial cable for a socket directly below (but about 3ft lower) passed through. Other electrician said it was wrong and shouldn’t be done. My take was that it is, at best, a bit of bad...

    Cord Grip for a surface mount pattress / back box?

    I know this is a bit of an odd one, so bear with me, I have an idea in mind, but many of the power strips I see are either a) crap b) stupidly expensive, c) lack mounting holes or d) all of the above. So given I have a fair number of 3 gang sockets and back boxes (bought for a job cancelled at...

    PVC Back Box w/ Multiple Knockouts

    Hi does anybody know of single / double PVC back boxes that have multiple 20mm knockouts like metal clad? Or are plain with no knockouts ? The ones with one 20mm and trunking knockouts don't really work as when cutting the 20mm hole the trunking entry normally splits even when bracing it.

Absolutely no slack on the cables. I’m quite amazed really as I’ve 10 to swap, some were okay, and the last one...

    25mm back box - Schneider Ultimate Slim Range
