EARTH BONDING
Earth bond the Multiswitch to the Earth Bonding Lug and/or the Earth
Terminal Bars using minimum 4mm² Earth Bonding Cable. It is best practise
to earth bond across all Multiswitches using a single unbroken Earth Bonding
Wire. To achieve this, strip away 3cm of the insulation of a length of 4mm²
Earth Bonding Wire.
See Figure 1.
Unscrew the Earth Bolt on the Earth Terminal Bar to provide enough clearance
to wrap the Earth Bonding Wire around the Earth Bolt.
See Figure 2.
Tighten the Earth Bolt and route the Earth Bonding Wire to all other Earth
Terminal Bars and terminate as detailed above. Make sure that the Earth
Bonding Cable is connected directly to the building’s PME.
