Hi any thoughts on this ?
Doing a periodioc on a commercial property with a restaurant and kitchen.Lots of metal tables in the kitchen (not fixed) gas ovens,dishwashers etc.
The circuits are rcd protected the main bonding to gas/water is ok
There has been installed a 6.0mm earth cable running round all the metal tables,sinks,hot/cold water then back to the board and connected to the main earth terminal.
Question - 1- why is this needed - because of rcd protection !! and 2 - could it cause problems in the event of a fault ??
