In an empty wharehouse where we're just starting work, theres a large supply coming in with its main earth using a 35mm earth cable. I'm going to use 25mm earth for bonding to the gas and water main, however the gas pipe is 3 inches across. And i havent done bonding with that size of earth and pipe before. How do I bond to it? Cheers
