Since the recent publication of BS7671:2018, there has been considerable dialogue within the temporary building industry regarding the use of flat-twin and earth or flexible cabling to provide a safe internal electricity supply.
It is widely believed that static units, i.e. buildings that are to remain in situ for lengthy intervals can be electrified using flat twin and earth cabling, whilst portable units that are regularly moved from site to site, must be always wired with flexible cabling.
Many of the UK’s manufacturers of temporary buildings are continuing to use flat twin and earth cables on buildings that are expected to remain on-site for long periods of time.
However, at Newspace, we have taken a different course of action. Following a considered discussion about which wiring option will be the safest for their customers, Newspace has concluded that from this moment and on all future buildings, static or portable, their electricians will only fix flexible cabling.
Newspace’s explain, “We thought about this very carefully. We have seen evidence of flat-twin and earth cabling beginning to fray and harden over time. This could develop into a safety hazard, so we took the decision to only use flexible cabling.”
“Using flexible cabling will make our buildings fully compliant with IET wiring regulations. This extra added value will give peace of mind to our clients and all users of Newspace buildings at no extra cost,” they added.
