A IP rated CU unit has been installed at a caravan site, which is screwed to a fence, but you have to climb over the fence to get to it and there is a 8foot drop into a beck right below the CU! There is onlt approx 1 foot of ground to stand on in front of the CU and then in has a drop into the beck, where you need to stand to be able to check CU is covered with undergrowth and is very slippy. I'm concerned that if something trips, then whoever goes to trip it back in will fall into beck!
Also the supply to the building is a TT system, it goes into a Metal Cu and then SWA underground to the Outside CU. It Does not a RCd until the outsdie CU. Doesnt reg require a 100mA RCD at the 1st CU?
