Quick Answer
The 0.8T or 1T mini excavator is ideal for NBN cable trenching — typically 200–300mm wide and 500mm deep. Both machines fit through residential gates and don't require a licence in NSW.
## Excavator Hire for NBN Cable Installation in NSW NBN cable installation requires a trench from the street boundary to the building — typically 200–300mm wide and 500mm deep. This is one of the most common applications for BuildHire's smallest machines, and one of the fastest jobs a mini excavator can do. ### Why Hire an Excavator for NBN Trenching? Manual trenching for NBN cable is slow, physically demanding, and expensive. A 0.8T or 1T mini excavator can complete a standard NBN trench (20–30 metres) in 1–2 hours. The same job by hand takes a full day or more. For NBN installers, tradies, and homeowners, hiring a mini excavator for NBN trenching is one of the highest-value uses of a 1-day hire. ### NBN Trench Specifications Standard NBN trench requirements (as per NBN Co installation guidelines): - Minimum depth: 300mm (conduit must be a minimum of 300mm below finished surface) - Recommended depth: 500mm (provides protection against future surface work) - Width: 200–300mm (sufficient for conduit installation) - Conduit: 25mm or 32mm PVC conduit (supplied by NBN installer) ### Machine Selection **0.8T mini excavator (750mm wide):** Ideal for very tight access — narrow side passages, small residential lots, or sites with limited manoeuvring space. The 0.8T's narrow bucket (200mm) is perfect for NBN trench widths. **1T mini excavator (900mm wide):** The most popular choice for NBN trenching. Slightly more productive than the 0.8T and fits through most residential side gates. ### Dial Before You Dig Before any NBN trenching, call 1100 or visit dialbeforeyoudig.com.au. NBN trenches often run parallel to or across existing underground services. Striking an existing cable or pipe is the hirer's responsibility. ### NBN Trenching in Concrete or Pavers If the NBN trench needs to cross a concrete path or driveway, a concrete saw is required before the excavator can dig. BuildHire does not offer concrete saws — hire one from a local tool hire depot before your excavator hire date. ### Combining NBN Trenching with Other Work Many tradies hire a mini excavator for NBN trenching and use the remaining hire time for other small excavation tasks — post holes, garden drainage, or site preparation. The 1T is versatile enough for most light residential applications.
NBN conduit must be a minimum of 300mm below finished surface. BuildHire recommends 500mm depth for better protection against future surface work.
BuildHire's minimum hire period is 1 day. For a standard NBN trench (20–30m), the 0.8T or 1T will complete the work in 1–2 hours — the remaining hire time can be used for other tasks.
