When it comes to electrical work, choosing the right conduit and fittings is key to keeping your job safe, neat, and long-lasting. Whether you’re wiring up a new home, upgrading an industrial site, or working on a commercial project, understanding your Conduits Fittings components helps you work faster and smarter. In this article, we are going to explain different conduit parts using simple language, but with professional insight. Let’s go through the most common types of conduits and a list that you’ll need for Aussie jobs!

Essential Conduit Types for Smooth Electrical Installations in Australia: 

1. Conduit Saddles (PVC, Metal & 316 Stainless Steel)

Saddles hold conduits securely in place on walls, ceilings, or other surfaces.

Types:

• PVC Saddles: Lightweight, easy to install, and best for indoor or dry areas.
• Metal Saddles: Strong and fire-resistant; great for tough jobs.
• 316 Stainless Steel Saddles: Excellent for marine or corrosive environments like chemical plants or coastal areas.

Pro Tip: Use stainless steel saddles for outdoor or wet areas to avoid rust over time. For quick installs, pre-drill mounting holes before fastening.

2. Conduit Couplings (Grey, White, and Orange)

Couplings are used to join two conduit lengths together to extend a run. This can be quite helpful when you have to expand shorter connections. 

Colors explained:

• Grey: Often used indoors or for data cabling.
• White: Common in homes; looks cleaner and suits indoor walls.
• Orange: Used for underground or high-voltage electrical jobs.
• Pro Tip: When working underground, you should always choose orange for easy identification and compliance. Then, you can add solvent cement for a secure, waterproof seal.

3. Sweep Bends (White, Grey, and Orange)

Sweep bends curve the conduit smoothly to guide cables around corners without sharp turns.

Why they matter: Sweeps help prevent cable damage and make pulling easier.

• Pro Tip: Use long-radius bends for easier cable pulls over long distances. You should stick to color coding for safety and fast job-site inspections.

4. Bends & Elbows (Grey, White, and Orange)

What they do: Like sweep bends, these help conduits turn corners. The difference? Bends and elbows are tighter and more rigid.

Use them when: Space is tight, or the angle needs to be precise, such as a 90° turn.

• Pro Tip: You should avoid overusing elbows. It can lead to many tight bends, which makes cable pulling harder. Therefore, you can always check if a sweep will do the job more efficiently.

5. Shallow Junction Boxes

These shallow junction boxes can house wire connections and protect them. You can use shallow junction boxes, where wall or surface depth is limited.

Best for: Wall switches, lights, and low-profile installations.

• Pro Tip: You should label your wires inside the box. It makes future maintenance much easier. And always use grommets to protect cables entering the box.

6. Deep Junction Boxes

Same as shallow boxes but deeper, allowing more space for wire connections and accessories.

Best for: Heavier wiring jobs, multi-core cables, or tight bundling.

• Pro Tip: If you have any doubt, then you should consider using deep junction boxes. A little extra space today saves a lot of hassle tomorrow. You can opt for flame-resistant materials to meet safety standards.

7. Conduit Reducers / Step Reducers

These connect conduits of different sizes from bigger conduit stepping down to a smaller one.

Where used: In transitions, like from a 40mm trunk line to a 20mm feed to a switch or outlet.

• Pro Tip: You can use reducers that match conduit materials to prevent cracking. It is important that you always seal properly to avoid moisture entry, especially in outdoor applications.

8. 40mm Square Junction Boxes

These boxes allow multiple conduits to connect at one point and provide room for joining wires.

Why they’re useful: Their square shape and size give more space for wiring than round boxes.

• Pro Tip: When working on an outdoor project, you need to mount the junction box securely and check its IP rating. You can use 40mm when working with thicker cabling or where more wire movement is expected.

9. Tee Fittings: Straight Tee, Inspection Tee, & Reducing Tee

Straight Tee

• What it does: Splits one conduit into two at a right angle.
• Best use: Running a branch line off a main conduit.

Inspection Tee

• What it does: Same as a straight tee but includes a removable cover for cable access.
• Best use: In maintenance areas where wires might need to be pulled or replaced later.

Reducing Tee

• What it does: Connects a larger main conduit to smaller branches.
• Best use: When splitting off different wire sizes or services from a main line.

Pro Tip: Always position inspection tees in accessible locations. When using reducing tees, clearly label different services (e.g., power, comms).

10. Plain to Screwed Adaptors

Connect plain (smooth end) conduits to fittings that have a threaded (screwed) end.

Why they matter: Some fixtures such as metal boxes need a screw thread for secure connection.

• Pro Tip: You can use thread tape or conduit cement to avoid loosening over time, especially in high-vibration areas. By choosing adaptors that are UV rated for outdoor jobs, you protect your client’s system from damage.

FAQS: 

What are the main types of conduit saddles, and when should I use stainless steel?
Conduit saddles come in PVC, metal, and 316 stainless steel. PVC saddles are ideal for indoor jobs and are easy to handle. Metal saddles work well in areas with fire risk or where extra strength is needed. Stainless steel (316 grade) is best for outdoor, marine, or chemical-heavy sites due to its rust-resistant properties. 

Why are conduit couplings color-coded in Australia?
Colors help indicate use: grey for indoor/data, white for residential, and orange for underground or high-voltage jobs.

What’s the benefit of using 40mm square junction boxes instead of round ones?
40mm square junction boxes offer more space for wires and allow multiple conduit entries from different directions. They are excellent for central wire hubs, particularly in industrial or commercial projects where cabling density is higher.

Are square junction boxes better than round ones?
Yes, square boxes offer more internal space for wiring and make connections more accessible.
