Introduction
PowerSeal products are a cost effective range
of switches and socket outlets designed for
external use with the necessary IP (water and
dust protection) rating established by an
independent test authority.
The socket outlet cannot be used while it is
raining since there is no protection while a
plug is in the socket but users would not be
operating most commonly available DIY and
gardening equipment in the rain.
The tough, impact resistant casings of this
range give good physical protection in
outdoor locations.
Water may accumulate outside the sealed
area. To ensure full safety wipe the face of
the socket before use.

2 Installation
This product must be installed in accordance with the appropriate
building and wiring regulations.
In all cases if there is a doubt as to how to proceed with an
installation consult a qualified electrician, your Local Authority’s
Building Control Department or the Timeguard Helpline
(020 8450 0515).
2.1 Cable Entry
Try to avoid siting the units in areas where there is direct sunlight for
any length of time.
Cable entry can be made via conduit into any of the 8 knock outs
on the top, bottom, sides or back of the back box. In all cases
ensure there is a drain hole at the lowest point of the conduit
system.
The knock out outline should be heavily scored with a sharp knife
before tapping out.
The appropriate sealing washers for the conduit in use must be
used to maintain the IP rating. The use of any knock outs apart
from the ones at the bottom requires that the lower drain holes on
the back box are opened and the IP rating may well be reduced.
The blind grommets may be used for cable entry at the bottom
20mm holes. They must not be used in any other position
(including the rear) or the IP rating may be severely prejudiced.
The blind grommets should be pierced centrally to give an
undersize hole of a similar shape to the cable cross section.
2.2 Fixing Back Box
Drill 4 holes according to the dimensions given on the rear of the
back box. Fix with round head no. 8 woodscrews or equivalent
using wall plugs if necessary. The length of the screw will depend on
the surface being fixed to, for example fixing to roughcast would
require a longer screw than fixing to brickwork.
2.3 Connecting Cables
Allow sufficient excess cable to wire up the socket, but not too
much to make it difficult to close the front plate onto the back box.
The RCD socket outlet should form part of a 30A ring main, or ter-
minate a spur off a 30A ring main.
In spur configuration we recommend feed cable of 1.5mmsq.
If the unit is to form part of a ring then incoming and outgoing
cables must be 2.5mmsq.
Use back box earthing terminals to maintain earth continuity
where required.
The RCD is a non latching version. If set,
it allows the contacts to open if the mains
supply is interrupted, a safety must for
applications such as gardening and power
tools.
The RCD unit fully complies with BS7288 and
the socket outlet to BS1363. The combined
unit provides protection against fire hazard
and rapid double pole disconnection from
electric shock for the appliance and cable
connected to it.
Note: RCD - Residual current device (formerly
known as an earth leakage circuit breaker).
