Frequently Asked Questions
What wire sizes work with the BS43 terminal?
The BS43 supports 1.5–2.5 mm² stranded copper conductors, equivalent to approximately 14–16 AWG, in line with blue insulation coding standards.
Is the BS43 compatible with M4 studs or screws?
Yes. The BS43 is engineered for precise installation on 4 mm (M4) studs or screws commonly used in compact terminal blocks and control installations.
Does the fork design suit tight spaces?
Absolutely. The fork profile allows clean installation beneath partially loosened screw heads and within densely populated control cabinets.
Which tool should I use for BS43?
A calibrated ratchet-style crimping tool designed for insulated terminals in the 1.5–2.5 mm² range ensures secure and consistent crimps.
Can BS43 be used with solid-core wire?
While optimised for stranded copper conductors, the BS43 may also be used with solid-core wire when properly crimped using suitable tooling.
What is the operating temperature range?
The BS43 is rated for continuous use between -40 °C and +105 °C, suitable for most industrial and control applications.
What does blue insulation indicate?
Blue PVC insulation signifies compatibility with 1.5–2.5 mm² conductors according to recognised international colour coding standards.
