Yep, the link is in post 7!

No, those only have overcurrent protection. These have a plug-in RCD supplied:

Note, you will need two to run all your appliances. Fryer on one reel and fridge and food warmer on the other.

o gosh im going mad lol, thanks

a 13A BS1362 (plugtop) fuse will happily carry 16A until the end of time.

For a short period and given the thermostats in the appliances will be turning them on and off during use I'd be inclined to just use a single good 4 way lead.

As other have said, if you get the reel type them make sure it is unwound completely

I agree but it's best to err on the side of caution as often at these events, other items end up getting plugged in to the extension reels!

You have to also consider whether the thermal cut-out would allow 16A through it or not?

hadn't thought about a thermal cut out, my excuse (if needed) is that my "good 4 way lead" would be 1.5 or 2.5mm cable and not include a thermal cut out

The 3,700 amp max draw would be slightly over 1.5mm core values albeit you can probably factor in diversity values.

I guess you mean 3,700 Watts not 3,700 amps.....:D

from an engineering pov the safety factors built into cable ratings are huge..... continuous max duty/high ambient temp/low heat transfer/20 years in service etc etc.

As an unrelated example, we recent ran a 160kW motor (so about 300A) using temporary 50mm cables (rated 167A) whilst we repaired some bars. Duty cycle was low (ish) and the cables were warm to the touch but nowhere near dangerously hot. As a permanent install I'd have gone for 120mm cable, for a couple of days 50mm was fine

Umm yes, 3,700 amps would be impressive!

Interesting re: your 50mm cables, on a more unrelated note I saw a cable spike being used today for the first time in ages, forgotten how loud they are and noticed that the engineers still poked it carefully even after spiking it.

Was thinking of being cheeky and asking them if the spiker had his firearms license but they were much bigger than me and I didnt fancy being a human joint in a 11kva 400/3ph cable(s).
