terminal up to outlet from balcony external perimeter, including the height of protection baluster, if any, is not less than 2 m.
(2)
Distances of not less than 500 mm shall be adopted in placing the terminals, due to the proximity to materials subject to the action of
products of combustion such as plastic gutters or waterspouts, wooden jetties, etc.) unless adequate screeening measures are taken for
the said materials.
