It’s not looking good is it.. There’s likely to be a few heads roll over this and fingers pointed in all directions.
With regard to electric supply, domestic mains is 230—240V here in the UK, totally different to the 415v 3-phase supply used in industry.
But, for the construction and service industry, apart from cordless battery tools, which were allowed, 110V CTE was normally used for portable site equipment, and became compulsory even for locksmiths and safe engineers for on-site works. I completed countless declaration papers for contract work undertaken for large companies who insisted on it.
seems like the rulings changed yet again though as part of a European ruling. Apparently 230V equipment is again permissible for on site use provided it is used with RCD protection. Apparently it come about as a result of increased volume of workers from Europe working in Britain and bringing their 230V equipment with them.
Im guessing this is the explanation for the Hilti DD350 being 230v and not 110v as would have been the norm a few years back.
It certainly did the job anyway..
