Kitchen Equipotential Bonding System
Equipotential Bonding in a Shower or Bathroom
Showers and baths provide an increased risk of shock hazard due to the reduction of body resistance ( skin wet ) and the possibility of contact with earth potential. Extraneous conductive parts and exposed conductive parts in an area containing a shower or bath are treated as being within zoned areas.
Bonding Clip
The type of bonding clip used is corrosion resistant and adjustable to fit several sizes of pipe. A locking device is provided to ensure that the clip cannot work loose through expansion / contraction caused by heating / cooling or by vibration. The pipe should be first cleaned to remove any residue from building materials or oxidisation that may have built up over years on an older installation. The clip should be tightly fitted and the locking device secured to ensure good electrical contact with the pipe. A terminal is provided for the electrical connection to be made. This connection must be properly terminated, taking into account the type and size of conductor(s) involved. A metallic label must be fitted with the words “SAFETY ELECTRICAL CONNECTION DO NOT REMOVE” embossed on it.
