    Is this single phase as well as 3 phase and what is it's power rating?

Recently it has started tripping the B40 MCB. It does not trip immediately so I don't think it is the inrush, plus it did...

    TP&N equipment rating

    TP&N voltage ratings for products, equipments etc are expressed alternatively as 440/250VAC or 250/440VAC (or 250/440 Vac etc), or in other representations. What is the "technically correct" format and in what standard/specification is it embedded? (is it IEC60050?). Thank you.

    Rating of RCD's

    I am an adult learner. I understand the theory behind the 30mA trip rating (for example) of an RCD but I need some help understanding what the 63A rating (for example) actually means. My understanding is that RCD's do not provide over current protection, that would be provided by MCBs (for...

    16, 32 and 63 as a rating

    Why are 16, 32 and 63 amps used as an MCB rating instead of 15, 30 and 60 amps? Best theory that I can come up with was when the UK switched to 230 volts this was to make up for the drop in voltage but have noting to back that up. Here are the ratings I'm familiar with: View...

    Hi all, I noticed on my consumer unit that the main switch is rated for 100Amps, however the total load of all the MCBs is over 150Amps! I appreciate that diversity COULD (?) be applied in that not every circuit would be simultaneously running at full capacity, but is the installation...

    Kitchen ceiling lights fire rating

    greetings :) Was curious about the ceiling lights in the kitchen if they were fire rated or not. Google was no help with model info. There’s an F in a triangle symbol on the side, but I don’t know if that means anything. Any ideas? Thanks, Gary
