Ed Davies Posted January 19, 2019 Share Posted January 19, 2019 You'd be very unlucky to get a 110 V shock off a 110 V supply, a 55 V shock is much more likely. A circuit breaker likely won't help much for shocks off a 240 V supply. A 30 mA RCD probably will save you, if it's working properly. Link to comment Share on other sites More sharing options...

Think you mean RCD. Link to comment Share on other sites More sharing options...
Onoff Posted January 19, 2019 Share Posted January 19, 2019 I've had a 110V belt up through my sweaty armpit working with my shirt off of an obscure bit of crane kit years back when I leant across it. Unpleasant is the word. Site trannies/kit are 55V to earth to limit the effect of a belt. Link to comment Share on other sites More sharing options...

epsilonGreedy Posted January 19, 2019 Author Share Posted January 19, 2019 When the kit arrives will I be able to cut a 75mm ducting hole through both the inner and outer blocks from one side? The footings have standard 100mm blocks with a 100mm cavity. I ask because it would be simpler to access the footings at the right depth from the internal oversight.

Very common DIY accident. Which is why ladders are for access only on proper building sites. If you want to work at height the you can't use a ladder as a work platform. Luckily we aremostly DIYers on here 1 Link to comment Share on other sites More sharing options...

Luckily we aremostly DIYers on here even more reason not to push the limits , if you get hurt doing and things go wrong house may never get finished you don,t bounce as well at 40+ as you did at 20. you are supposed to get smarter with age not more stupid. how many of your ladders are actually tied to something ?

nod Posted January 20, 2019 Share Posted January 20, 2019 Your feet need to be planted firmly when core drilling Even above a ground floor window You neeed to put a secure deck up My advise would be to get the bathroom wastes and fans done while the scaffold is still in place If you are rendering You can get everything done from the inside prior to rendering It always makes me laugh when we visit the build shows and they are selling the adjustable ladders Bbbb or whatever aproved It is so unusual to see a step ladder onsite now As someone has already stated Access only I can still rember roofs on sites being felted and tiled without any scaffolding Just one piece pile ladders Scarey We all need to be careful As one slip could end our selfbuild Link to comment Share on other sites More sharing options...
