The EC7885A must have an earth ground providing a connection between the subbase and the control panel or the equipment. The earth ground wire must
be capable of conducting the current to blow the 20A fuse in event of an internal short circuit. The EC7885A needs a low impedance ground connection to the
equipment frame that, in turn, needs a low impedance connection to earth ground. For a ground path to be low impedance at RF frequencies, the connection
must be made with minimum length conductors having maximum surface areas. Wide straps or brackets rather than leadwires are preferred. Be careful to
verify that mechanically tightened joints along the ground path, such as pipe or conduit threads or surfaces held together with fasteners, are free of
nonconductive coatings and are protected against mating surface corrosion.
