FAQs

What are C connectors used for in electrical earthing?

C connectors (also called C clamps or C-type compression connectors) are specifically designed for tapping into and joining stranded copper conductors in earthing applications without cutting the main cable. These copper connectors enable tap and parallel connections for establishing low-impedance earthing systems, connecting earth grids, and bonding applications required under AS/NZS 3000:2018.​

Do earthing and bonding products need to comply with Australian standards?

Yes, all earthing and bonding installations in Australia must comply with AS/NZS 3000:2018 Electrical Installations (Wiring Rules), which sets out specific requirements for earthing conductor sizing, equipotential bonding, and connections to building reinforcement. Licensed electricians must ensure earthing products meet these standards for safety, equipment protection, and legal compliance.​

What size earthing conductor do I need for bonding applications?

Earthing conductor size depends on your specific application and the size of electricity supply cables. For equipotential bonding to concrete slab reinforcement in bathrooms and showers, AS/NZS 3000:2018 Clause 5.6.3.2(b) requires a minimum 4mm cable. For main earthing connections and building framework bonding, conductor sizing is determined by the installation’s electrical supply capacity.​

Can I use C connectors for both residential and commercial projects?

Yes, C connectors and compression clamps are suitable for residential, commercial, and industrial earthing applications. These versatile connectors accommodate various conductor sizes (from 7.5mm² to 895mm² depending on the model) and are designed for buried earth grids, overhead connections, and general grounding systems across all project scales.​

How quickly can I get earthing products delivered in Australia?

iSupply Electrical offers same-day pickup from our Fairfield East, NSW location for urgent project needs, plus fast Australia-wide delivery within 1-6 days depending on your location. Licensed electricians can order online or contact us directly for bulk pricing on earthing and bonding accessories to keep projects on schedule without delays.​
