Where the electricity supply is obtained from a generator set, the
TN-S earthing system should be used.
(4) Inspection, testing and maintenance
An owner of the temporary installation should ensure that the electrical
equipment and apparatus are maintained in a safe and proper working
condition at all times.
A registered electrical worker should be appointed to be responsible for
the safety and any alteration or extension of the installation. The name,

26L Hot Air Saunas Installation
(1) General
The particular requirements of this Code should apply to:
(a) sauna cabins erected on site, e.g. in a location or in a room;
(b) the room where the sauna heater is, or the sauna heating appliances
are installed. In this case the whole room is considered as the sauna.
The requirements of this Code do not apply to prefabricated sauna cabins
complying with a relevant equipment standard.
(2) Classification of zones
The zones specified below should be taken into account (see Figure
26(2)):
(a) Zone 1 is the volume containing the sauna heater, limited by the
floor, the cold side of the thermal insulation of the ceiling and a
vertical surface circumscribing the sauna heater at a distance 0.5m
from the surface of the heater. If the sauna heater is located closer
than 0.5m to a wall, then Zone 1 is limited by the cold side of the
thermal insulation of that wall.
(b) Zone 2 is the volume outside Zone 1, limited by the floor, the cold
side of the thermal insulation of the walls and a horizontal surface
located 1.0m above the floor.
