WARNING
ELECTRIC SHOCK
– An electric shock can be fatal; electrical connection work may only be carried out by a
competent person. The earth conductor must be correctly installed and reliably connected. This device must
b equipped with an over-current protection device of maximum 32 Amps (B32).
8.2.1
Cable and Gland Requirements
The Cross Sectional Area of the cable used should be between 4mm
2
and 10mm
2
. The gland size should be a
minimum of 16mm and a maximum of 25mm. Generally, a stuffing gland can be used. SWA CW outdoor glands
may be used for armoured cable. The size of cable and gland used is the responsibility of the installer and
should be determined on an install-by-install basis dependant upon install specifics.
8.2.2
Strip Length
The main terminals are designed to work with wires with a diameter up to 16mm
2
.
Insert the mains cable through the installed cable gland (if not already done so). Strip
back outer sheath ensuring all cables reach the terminal blocks (leaving a little excess).
Strip back all coloured cables approx. 18mm.
If using hard wired CT clamps now is the time to insert these too (we recommend a specialist cable gland that
can accommodate multiple cables whilst still maintaining IP integrity, or two separate cable glands to ensure
zappi
remains sealed).
