Whats more shocking, the listing or the inside switch outside.

So Kerching did you win the bidding?

The Adiabatic equation does not apply to bonding. By current regs you are allowed to have one unbroken run of 10mm to bond both gas and water. In an electrical sense I don't see the difference between that and having a 6mm to water, 6mm to gas and all cross bonded by a big metal manifold at a gas boiler. To my mind it's then a 'bonding ring' so will take a hefty current.

Except that its a bonding conductor, not an earth, so it's there to equalise potential difference, not carry any 'hefty' currents.

6mm is not deemed adequate by current regs - and I don't get this ' no signs of thermal damage so its ok' comment.

If an installation has been fault free for 20 years there won't be signs of thermal damage - doesn't mean the main bonding is adequately sized.

Upgrade to 10mm every time .... 16mm tails now requires 16mm main earth not 10mm that many sparks believe so therefore 6mm not adequate....

Must admit, I always check the bonding on every quote I attend. Put simply, in order for me to work on the installation and certify it if the bonding is absent / inadequate in size then it gets replaced at the customers expense. Just a general rule of thumb I apply which when explained to the customer properly they understand.

I always carry the esc leaflets for bonding which helps to explain at quote stage that it HAS to be done. The leaflet helps no end and they don't think your doing unnecessary work at their expense
