Having an updated consumer unit in an outdoor location is essential.  Where water is present there is a greater risk of shock and corrosion of the metals on the connections etc.  In this installation there was added risk had conductive pipes coming into the  building, a garage.  So an earth rod was required to satisfy regulations.  

  1. a consumer unit with 30ma RCD protection
  2. Earth rod with a Ze value of 0.45 (well within safety limits)
  3. Certificate and building notification included in the price.

The result is a safe and reliable electrical installation outside for washing machine and other appliances.
