Frequently Asked Questions
What wire sizes are compatible with the BS53 terminal?
The BS53 supports 1.5–2.5 mm² stranded copper conductors, equivalent to approximately 14–16 AWG, consistent with blue insulated terminal colour coding.
Does the BS53 fit M5 studs or screws?
Yes. The BS53 is engineered for precise installation on 5 mm (M5) studs or screws commonly used in panel wiring and distribution blocks.
Is fork-style suitable for tight terminal setups?
Absolutely. The fork profile allows straightforward installation beneath partially loosened screw heads and within crowded panel layouts.
Which tool should I use with the BS53?
A calibrated ratchet-style crimping tool designed for insulated terminals in the 1.5–2.5 mm² range ensures consistent and secure crimps.
Can the BS53 be used with solid-core cable?
While optimised for stranded copper conductors, the BS53 may also be used with solid-core wire when properly crimped using suitable tooling.
What is the operating temperature range?
The BS53 supports continuous operation between -40 °C and +105 °C, suitable for most industrial and control applications.
What does the blue insulation signify?
Blue PVC insulation indicates compatibility with 1.5–2.5 mm² conductors according to recognised international terminal colour coding standards.
