Another rather basic question: is FP cable any less likely to suffer damage by nibbling than PVC? Location is the semi-enclosed eating area in a camping cabin environment. Cables are to be installed on roof truss timbers; basic plus emergency lighting. Our resident farmer wearing his pest control hat, reckons the risk of 'critters' being interested in getting up there is quite low; there is no evidence of their presence in the area thus far. As site management is highly resistant to a conduit system on the grounds of appearance, I have few options (and walking away is not one of them). I guess I'd be happy enough using MI, but costs and borrowing of tooling would both be difficult. Anyone in West Oxfordshire if that is the advice?
