my floodlight was 230V. i just changed the bulb for a 110V and changed the plug

supersparks said:also allowed is 230v used on sites
but must have RCD protection at 30mA
and also disconection time max of .2seconds if i remember correctly.

i have notes someware detailing all this and im 98% sure they allow rcd protection at 30mA, at the discression of the HSO on the site....
and 0.2 disconection is the time allowed on site for instant disconnection

kendor said:One thing missed in the replies apart from the lower voltage is the inherent safety of the transformers used, in being what's called double wound and therefore the output has no reference to the input mains and the earthing system of the normal mains in effect the output supply is isolated and unique to the power tool connected.

I'll bet there are plenty of plumbers, carpenters, decorators, kitchen fitters, gardeners etc who use 230V tools when they are working in someone's house or garden....
possibly 230ban-all-sheds said:True.
If, OTOH, you only ever worked in occupied, domestic houses or similar, and never "on site", would you buy 230V or 110V tools?
then they have changed since i was on sites the centre tap was never wired to the supply earth.andrew2022 said:kendor said:One thing missed in the replies apart from the lower voltage is the inherent safety of the transformers used, in being what's called double wound and therefore the output has no reference to the input mains and the earthing system of the normal mains in effect the output supply is isolated and unique to the power tool connected.
no. 110V Tx are centre tapped to earth. it is not seperated

It's called email and letters, as well as phone calls sometimes, but also due to things I have done in the recent past I have had reason to be in the same room as many of those people I mentioned in my earlier post, and I simply asked the question..perhaps I am just a nosey bar steward? or it could simply be that as a former Company Director responsible for the Health and Safety of our employees I took a personal interest in HSE Guidelines and related Legislation, as I did when a Consultant Project Engineer running a team of Guys a few years back..take your pick.
All 230V and 400V supplies on Site must be ultimately protected by an RCD, usually in the Temporary Dis Boards used to feed things such as site offices, Transformers, Canteens etc. These RCD's are usualy of the Variable time, Variable Trip type so they can be tailored to the site in question to give maximum protection with minimal nuisance tripping. I think that some of these rumours about the use of 230V on site has arison from this use of RCD's onsite.
If you think about it, 230V and 400V are used on site, as mentioned, to power site offices and the 110V transformers for tools and lighting as well as the afore-mentioned area floodlighting, so it is not a total ban. This is where many may have been confused by the regulation change a number of years ago that meant these had to be RCD protected. However from what I have been told, as stated in the earlier post, the use of 230V power tools on a construction site is still illegal in the UK and will remain so for the forseeable future.
