Approaching the BSS, and I have a concern over the above. I only have a Paloma and a Vanette oven. The Paloma has it's own isolator, but there isn't a seperate one for the oven (or if there is, I can't find it!). The BSS reads as though seperate isolators are compulsory - is this the case? Or is it a case of 'in an ideal world'?The fitout is original, including the oven (1990 nb, btw) and the boat has obviously satisfied requirements before. The trouble is, there's no realistic way of fitting one close to the appliance either.
