static caravan

Just 2 queries-
First of all I've never worked in a camp site and don't expect I'll ever want to.
These questions are just for curiosity and nothing else. My mate who is a relatively new sparks asked me to look at some work that we could possibly do together. So I went round, it was all a bit finicky for me so I declined.
Anyway while I was there I noticed a heater wired in 1mm t&e. While basic ohms law indicates this purely resistive load was ok, while I was at home reading up on caravan electric regs it indicates a minimum cable of 1.5... So is this correct? Or am I reading this wrong?
Also there were no rods placed beside each fused commando module for each pitch, and I would have thought this would have been the norm. So again, do they not need to be tt'd? Am I reading the regs wrong again? Please point me to the appropriate section if I've misinterpreted the regs. Thank you

could be a TN-S, then you are allowed to use existing earthing. it's TNC-S that you have to isolate the caravans from and TT them.

Hi Scornio,

You tagged your post onto the end of another thread which had no relevance to your questions so I've made it into a thread of its own for you.

I take it you mean touring caravans , as regards the internal wiring within them , is this correct, because if so the stranded flexible cable should be used , and yes 1.5mm2 is the usual cable used within the caravan ,
