Buy Electrical Tape — Electrical Tape for Professional Use

Electrical tape is an essential component on any worksite, ensuring safe, reliable insulation for wiring and electrical connections. At MJS Electrical Supplies, we offer a comprehensive range of electrical insulation tape options designed for durability, compliance, and ease of use. Whether you’re looking for black electrical tape, multi-colour electrical tape, or premium-grade electrical insulation tape, our selection supports every trade requirement.

High-Performance Electrical Tape for Every Application

Electrical tape is relied upon for bundling, insulation, and identification of wiring. Our range is selected for performance in demanding environments, giving tradies confidence on-site.

Durable & Compliant Materials

We supply electrical tape manufactured from high‑quality PVC with strong adhesion that withstands heat, moisture, and abrasion. Designed for safe, general-purpose electrical use when applied in line with Australian wiring practices, these tapes offer dependable insulation and long-term reliability in residential, industrial, and commercial environments.

Options for Colour Coding & Identification

Alongside black electrical tape, we offer electrical tape in multiple colours, ideal for phase marking, safety identification, and organisation. Rainbow‑colour packs make circuit identification and organisation easier, supporting clear on-site labelling in line with standard Australian wiring conventions.

Choosing the Right Electrical Insulation Tape

Selecting the appropriate electrical insulation tape depends on the environment and application. Our range includes general-purpose tapes for everyday tasks, as well as heavy-duty options for demanding conditions. Rainbow electrical tape should always be used as a supplementary insulating and identification material — not as a substitute for compliant joining or wiring methods.

Key Features to Consider

Adhesive strength: Ensures the tape stays in place, even in high-temperature or high-vibration areas.
Thermal resistance: Quality tapes resist temperature fluctuations without hardening or peeling.
Flexibility: Allows easy application around tight bends and irregular shapes.
UV and moisture resistance: Essential for outdoor or exposed installations.

FAQs

1. What is electrical tape used for?

Electrical tape is primarily for insulating, bundling, securing, and marking electrical wiring. PVC electrical tape provides a flexible, electrically resistant layer that helps protect conductors from accidental contact.

2. Is electrical tape suitable for electrical insulation?

Yes — PVC electrical tape provides supplementary insulation for wiring, helping protect conductors and bundling cables. For permanent joins or repairs, licensed electricians must use approved connectors or methods as required under AS/NZS 3000.

3. Can electrical tape be used on live wires?

No. Never apply electrical tape to energised wiring. Always isolate the power before carrying out any electrical work, making sure it’s in line with general safety requirements and workplace electrical safety procedures across Australia.

4. What temperature can electrical tape withstand?

Most quality PVC electrical tapes can handle temperatures ranging from 80°C to 105°C, depending on the brand. High-temperature or specialised tapes may be rated higher. Always refer to the product datasheet for accurate performance values.

5. What’s the difference between black electrical tape and coloured electrical tape?

Black electrical tape is primarily used for general insulation and bundling, while electrical tape in multiple colours (also known as rainbow electrical tape) is great for circuit identification and phase marking. Colour identification practices generally follow established Australian wiring conventions.

6. Can electrical tape be used outdoors?

Electrical tape is suitable for outdoor use only when it forms part of a protected wiring system. Standard PVC tape may degrade when exposed to UV radiation, heat, or moisture; therefore, outdoor wiring must still comply with AS/NZS 3000 requirements for mechanical protection, such as the use of conduit or enclosures.

7. Is electrical tape waterproof?

PVC electrical tape is moisture-resistant, but not waterproof. It protects against incidental moisture only. In areas exposed to heavy or continuous moisture, compliant enclosures or sealing methods — not tape alone — must be used.

8. Does electrical tape meet any standards?

Some electrical tapes comply with international insulation or performance standards, but this varies between brands. Always check the product specifications to confirm any ratings or test standards the manufacturer declares.

9. Why does electrical tape come in different grades?

Different grades offer varying levels of:

adhesive strength
thermal performance
dielectric strength
abrasion resistance

Higher-grade tapes are often suitable for commercial and industrial installations where longevity and reliability are essential.

10. How long does electrical tape last?

Longevity depends on environmental exposure, adhesive quality, and the thickness of the tape. Indoors, trade-quality PVC electrical tape can last for several years. In outdoor or demanding environments, the lifespan may be shorter unless the tape is for harsh conditions.
