FILOform’s WM range of mains branch connectors has been designed to accommodate three or four core sector shaped stranded conductors in the ranges specified in the table below: 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 specilised equipment or techniques are required.
These connectors can also accept stranded circular conductors to BS 6360 (copper) and BS6791 (aluminium) in the main and / or branch sides of the connector in the following ranges;
Material – Aluminum Alloy
Fitting instructions
Separate the main cables 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 5mm. Thoroughly abrade the exposed conductor and loosly 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 possitivley 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 a 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 16mm² 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 to improve the electrical stability of the interface connection.
