The number of cables and circuits that can be safely installed in a conduit or wiring enclosure depends on several factors, including the size and type of the conduit, the type of cables being installed, the current carrying capacity of the cables, and the ambient temperature.
Our conduit calculator is intended to be used as a guide for determining the safe number of cables and circuits that can be installed in a conduit or wiring enclosure without causing damage.
The cable types and sizes used in the calculator are based on manufacturer’s catalogue nominal sizes for cables conforming to AS/NZS 5000.1 and AS/NZS 5000.2.
The conduit sizes and types used in the calculator are based on nominal bore dimensions determined from AS/NZS 2053.2 (rigid UPVC), AS/NZS 2053.5 (corrugated), and AS/NZS 2053.6 (profile wall smooth bore).
The calculation method described in the calculator can be applied to other combinations of circular and non-circular enclosures, and cables of different types and sizes within the same enclosure, as long as the shape of the cables and enclosures are compatible.
It is important to note that the number of cables determined by the calculation assumes that the enclosure is relatively short in length, free of obstructions and distortions, and that the quantity and arrangement of impediments, such as bends, is minimized. If these conditions are not met, the number of cables should be reduced, and measures should be taken to ensure that the maximum cable pulling tension and bending radius are not exceeded.
The calculation for the number of cables does not consider the effects of grouping cables on current-carrying capacity, temperature rise, and voltage drop. Therefore, AS/NZS 3008 provides de-rating factors for grouping that need to be considered in determining the suitability of circuits.
It is recommended to follow the manufacturer’s instructions and the applicable codes and regulations for your location when installing cables and circuits in a conduit or wiring enclosure.
The conduit calculator is provided for informational purposes only, and we make no warranties, express or implied, regarding the accuracy, reliability, or completeness of the information provided.
We are not liable for any damages, including but not limited to direct, indirect, incidental, punitive, and consequential damages, arising from or related to the use of the conduit calculator.
The user assumes all responsibility and risk for the use of the conduit calculator and the installation of cables and circuits in a conduit or wiring enclosure.
The user is responsible for verifying the accuracy of the calculation and ensuring that the installation complies with the applicable codes, regulations, and manufacturer’s instructions.
We recommend that you consult a licensed electrician or engineer before installing cables and circuits in a conduit or wiring enclosure, especially for installations involving complex or high voltage systems.
By using the conduit calculator, you agree to release us from any and all claims, damages, and liabilities arising from or related to the use of the conduit calculator and the installation of cables and circuits in a conduit or wiring enclosure.
