Plug in RCD 230V or 110V transformer

Former Community Member

I'm curious to see what peoples opinions are on the two different options available for safer power tool use either using 110V tools with a site transformer alone or 230V tools however using these with the plug in RCD. 


I'm aware of the center tapped site transformer splitting the voltage into 55V so there is the arguement that it's only 55V pushing through your body, vs the RCD option, you're exposed to the potentially full 230V but the RCD cuts the supply almost instantly. However this is based on the RCD actually working and detecting a fault and even if it does perhaps even that brief exposure to 230V may be enough for some people to be fatal. Then again 55V maybe enough for some people too to be fatal. 


Thought?

    You do need to stop folk trying to fit RCDs to the RLV system though ?

    I think large sites where 110V can be centrally generated  it certainly makes sense, rather less so for jobbing builders working in peoples homes, the transformer is just another luggable thing to get damaged or to give someone back problems.

    you can buy them, designed to wire into the outgoing socket side of a portable unit. but I have seen them fitted to the 230v plug too


    in a domestic setting, I think there should be little use for mains hand tools now battery tools are so good. I do agree that a transformer should only really be set up once a day, if it needs moving more than that, its time to look at alternatives
