Insulation piercing connectors (IPCs) form electrical branch connections on compatible insulated conductors. They are specified separately from the clamps that mechanically support an aerial bundled cable. Use this guide to prepare the main-line and tap-conductor information needed for an ABC branch connection enquiry.
Connection requirements for ABC networks
Main-to-tap connections
An IPC connects a specified main conductor to a compatible branch conductor. Its contact system pierces the insulation when installed according to the selected model’s instructions. Main and tap conductor ranges must both be checked.
Service branch connections
For a service take-off, identify the conductor material, cross-section, insulation and circuit requirements. The connector’s electrical rating and connection configuration must suit the application.
Branch assembly accessories
Check which end caps, seals or other accessories are required by the selected connector design. Mechanical anchoring and cable support must be provided by suitable fittings, not by the electrical connector.
Information needed to select an insulation piercing connector
| Selection item | Details to provide |
|---|---|
| Main conductor | Material, cross-section, construction and insulation type. |
| Tap conductor | Material, cross-section, construction and insulation type. Check this independently of the main conductor. |
| Electrical duty | System voltage, required current rating and the project or utility specification. |
| Connection arrangement | Number of branches, conductor layout, access space and whether each side is insulated or bare. |
| Environment | Outdoor exposure, sealing requirements and any specified corrosion or weathering tests. |
| Procurement details | Required quantity, destination, drawings and requested test documentation. |
Check compatibility before ordering
A connector’s stated cross-section range does not by itself confirm suitability for every cable. Verify conductor material compatibility, insulation construction and electrical ratings against the specific model datasheet. Aluminium-to-copper connections require a connector explicitly suitable for that combination.
Installation requirements, tightening torque and any shear-head operation depend on the selected model. Follow the manufacturer’s instructions and the project’s electrical safety procedures. Do not assume a connector is reusable or suitable for live installation.
Frequently asked questions
Can an IPC also hold the cable tension?
An IPC provides an electrical connection. Use appropriately rated tension or suspension fittings for mechanical cable support.
Can one connector cover different main and tap sizes?
Some models cover a range on each side, but those ranges may differ. Provide both conductor sizes so the correct combination can be checked.
What should I send for a quotation?
Send the main and tap conductor datasheets, system voltage, required quantity and a drawing or photo of the intended connection. Include a preferred model or utility specification if you have one.
