Bonding is particularly important for bathrooms, swimming pools and fountains. In pools and fountains, any metal object (other than conductors of the power circuit) over a certain size must be bonded to assure that all conductors are at the same potential. Since it is buried in the ground, a pool can be a better ground than the electric panel ground. With all the conducting elements bonded, it is less likely that electric current will find a path through a swimmer. In concrete pools even the reinforcing bars of the concrete must be connected to the bonding system to ensure no dangerous potential gradients are produced during a fault.
