    "Safety Electrical Connection" metal labels

    Does anyone know a source of just the metal labels that are attached at earth clamps? Every time I need to replace a missing label, I'm taking a label from a new clamp, and throwing the clamp away, which seems a bit wasteful. I'd love to buy a bag/box of 50 or 100 of the metal labels.

    Metal web / posi joists

    I don’t work on many new builds and the builders I usually work for don’t use them, so this is the first time I’ve come across posi joists at work. I suspect I know the answer as to what usually happens here when running cables - ie they’re just lashed in ‘bow and arrow’ style, but does anyone...

    hi guys So I'm tasked with replacing plastic saddles in communal areas. App D in the OSG says saddles can have a max spacing of 1.5m apart. I know from past experiences that any conduit passing over must have a metal saddle in place. So was wondering will it be OK to replace the plastic...

    Hi guys, I had to carry out some alterations to a domestic installation the other day and was pleasantly surprised when having to run a new circuit how neat the CU was.

    I have 3 circuits (microwave, disposal, and dishwasher) entering a metal box where the THHN wire will be spliced to Romex. I spent half an hour reading 2020 NEC Article 250 but didn't see multiple circuits specifically addressed. To ground the box do I just need to pigtail off of one circuit's...

    Dado metal trunking

    Looking to put in some dado style trunking for a few power circuits and some Ethernet sockets, ideally metal type from a fire/EMC point of view. I had though of using the Marshall-Tufflex "System 130" (or maybe the bigger 170) steel system but wondered if the folks on here have any better...
