The Hepworth WM range of mains branch connectors has been designed to accommodate three or
four core sector shaped stranded conductors in the ranges specified above.
The connector employs the proven shear-head screw principle to ensure that a consistent and
reliable connection is achieved. Fitting is completed by the use of orthodox hand tools only, and no
specialised equipment or techniques are required.
Each connector is supplied in a sealed pack together with fitting instructions, details of which are
included in the technical data overleaf.
Secondary Application
These connectors can accept stranded circular
conductors to BS 6360 (copper) and BS 6791
(aluminium) in the main and/or branch sides of
the connector in the following ranges: -

Fitting Instructions
Separate the main cable cores sufficiently to allow the yoke section to be fitted around the conductor
and strip the insulation from the core equal to the connector length plus 5 mm. Thoroughly abrade
the exposed conductor and loosely assemble one side of the connector around the core by fitting the
bridge piece, inserting the pressure pad and tightening the main screws until the connector is
positively located. Set and locate the branch core, then cut to length, strip insulation to suit and
thoroughly abrade the exposed conductor before assembling into the connector as described above.
Complete the operation by tightening down the mains screws consecutively, one turn at a time, until
both heads shear, then repeating the operation for the branch screws.
It is suggested that conductors below the minimum range requirements of 16 mm2 are doubled and,
if needed, redoubled to achieve the required cross-sectional area and, if copper conductors are to be
jointed, they should be wrapped in brass gauze in order to improve the electrical stability of the
interface connection.
