Marquee electrial leads

As readers of the marquee forum will already know there’s been some debate about the type of electrical leads we should be using in the marquee industry.

Essential Supplies kindly forward this article to me recently which discusses several marquee related issues but the main bit of interest for me was this:

“The [arctic] cable can often be seen supplying caravans or used at live musical events, it can even be purchased from DIY shops in the form of a ready made extension reel with BS 1363 13 A accessories for use at 230 V 1Ø. As can be seen from Table 7B of BS 7540, the cable was not designed for and is not suitable for these purposes.”

My understanding of this is that despite their wide spread use arctic cables shouldn’t really be used for temporary installations in marquees. Instead we should be using HO7 RNF cable instead (much more expensive).

In my eyes that doesn’t mean we should replace all of the arctic cable we currently use but when it comes to ordering new/replacements we should then go over to HO7. Like everything on here this is just my opinion and it’s a judgement call for you to make yourself, I just think it’s worth highlighting to people.

Thanks for reading
