Note that in England and Wales the Building Regulations require a terminal guard to be fitted if the terminal is less than 2m
(6ft 6in) from the level of any ground, balcony, flat roof or place to which any person has access and which adjoins the wall
in which the outlet is situated. A suitable guard assembly is available from Robinson Willey Limited. The part number is
994371. In Scotland, although the Building Standards (Scotland) do not require a terminal guard to be fitted, the fitting of a
guard as detailed above is recommended.
