Cable sized to the standard — every time.
Cable sizing to AS/NZS 3008, voltage drop, protection and arc-flash safety — for the electricians who wire pump stations, bores and treatment plants.
Electrical & solar in Tenselo
A short introduction to what Tenselo covers in this category.
10 mm² Cu cable
AS/NZS 3008 · 40 A Type C MCB · 415 V 3-phase
These figures come from the Tenselo engine. Every result Tenselo produces shows the inputs it used and the method behind it, so the work can be checked rather than taken on trust.
Why it matters on the job
AS/NZS 3008 compliant
Current-carrying capacity and volt-drop worked to the standard, with the earth from Table 5.1.
Protection that coordinates
MCB / fuse rating sized to the load and the cable, not picked by feel.
Arc-flash & fault aware
Fault-loop impedance and arc-flash tools keep the install safe and certifiable.
