I'm sure speed will explain but its a 110 volt multi socket. The yellow box is a 110 transformer and the flying saucer an extension cable reel. Now I want an explanation as to why they have 110v on site in the UK?
Health and safety. 110 don't kill you.
Umm yeah it can just less likely than 240v. Most the time 240v won't kill you either you just have to be unlucky. Touch wood I have been lucky about 10x when I have had a 240 shock. The only danger is really if it gets hold of you so a
RCD should be used so this can not happen.
240v with RCD is just as safe as 110v but these stupid big site don't allow it even though your are actually aloud 240v with
RCD by law on site. Just no big sites allow it. I hate 110v and refuse to go down that route.
Just like Dean said why is their a 240 lead next to the 110v transformer in the picture defeats the object.
This happens a lot on all the jobs I go on 240v leads ever where and then people have 110v transformers running their tools all because if they get a job on site they need 110v tools. Ideally you buy 2 of every tool 110v and 240v soo you can work on site and off site.
I personally went down the 240v route because of two main reason
1. The tools are more powerful and run smoother
2. I hate carrying transformers about they are heavy and a pain.
Other reasons are you get a lot of power drop with 110v if some 1 else starts a tool up on the same lead 240 or 110 your tools looses power. If you have lights running on 110v they keep dimming when you start a tool up. To over come this you need a bigger and more powerfull transformer or multiple transformers more stuff to carry about. Bigger transformers are really heavy.
