Hi I am also new to this forum.
Ive recently had my third elecsa assessment. Dont get too worried. Most of the guys are pretty friendly and rememeber, they're not the gestapo, they want your money at the end of the day. You're worth £500 a year plus to them and if they fail you, they know you can just go to napit instead. Its a business transaction and you're the client. As long as you can provide all the things on the checklist (if you cant, you have a month after to do so) and prove your basic knowledge of things related to domestic work you'll be fine. They usually ask you the following type of thing: Max RCD trip time at 1x and 5x 30ma, Max Ze on TNS, TT, TNCS. MAX Zs on 32A MCB etc. What size main tails should be, what size Main earth and bonding should be. It doesn't matter if you don't know everything. On my first Assesment I had only worked as an electrician, full time for about 2 years. The job I showed them was just a bathroom where I had installed lights, fan, UF heating, towel rail etc. I had used new lighting and 20A radial circuits fed from a 2 way RCD board (they do like to see some form of consumer unit installed by you) If they do pull you up on minor things they will just write it down as advisory. At the end of the day, they don't want to fail you, they just want to help you improve and work to the regs as closely as possible.
