And I'll ask again why do you keep banging on about what happens outside the UK?This appears to be the current understanding:
- There are no requirements in the Wiring Regulations for gas appliance supplies to be fused at 3A.
- There are no requirements in any gas regulations for gas appliance supplies to be fused at 3A.
- The Wiring Regulations do not make it mandatory to abide by any manufacturer instructions.
- The Gas Safety (Installation and Use) Regulations (I'm assuming it is they) do make it mandatory to abide by any manufacturer instructions.
- Some gas appliance manufacturers require 3A fusing in the UK.
- Some gas appliance manufacturers do not require 3A fusing outside the UK.
- Nobody knows why #5 is justified, particularly when #6 applies to the same appliance sold elsewhere.
- Notwithstanding #7, #4 means that observing #5 is not optional.
It is totally irrelevant when we are in the UK and have to abide by UK rules/regs. Apologies to those who are without.
AFAIC only #4 & #5 are relevant to any discussion.
