[QUOTE="dobo99, post: 56817, member: 31"] Hi been scratching my head on this for a couple of days now. Situation is this, doing a rewire of a church with living accomodation attached, the church itself has been rewired now onto the living accomodation. There are a total of three boilers providing CH/HW to the church and house, a big floor mounted one which does the church only, a normal size floor mounted one which does part of the house and also some of the side room`s off the church and finally a back boiler which does the rest of the house. Problem i have is the Gas main comes in off the road to a large meter which is mounted on the community centre wall which is about 20M from the church and is completely seperated (ie not attached to the church) then it goes underground again and reappears in two seperate places a largeish steel pipe goes into the boiler house to feed the large floor mounted boiler and also a 28mm copper appears about 10m away from the steel pipe (the joint is not visible) and feeds the normal sized boiler, the back boiler and oven. There are two seperate single phase T-N-S supplies one feeds all of the church/offices and the other does the house. Question i have is where to bond the gas mains and off which supply? It`s got me stumped :( Hope someone can help me [/QUOTE]
