Prior to installing cables it is recommended that the route be inspected.
This will 1. Avoid bends and pulling tensions that exceed the limits of the cables. 2. Avoid clearance issues and jamming of the cables inside conduits. 3. Tell you which direction of pull (forward or reverse) will be the best. 4. Assist with placement and pulling force requirements for winching or push/pull machinery.
The new maximum demand module provides fast and accurate calculations for loads in accordance with rules from the Standards and for custom loads. An ingenious automatic phase balancing algorithm ensures maximum demand and phase imbalance are both minimised.
The purpose of this document is to provide a better understanding of Fault Loop Impedance, also referred to as Earth Fault Loop Impedance so that the requirements of AS/NZS 3000 Wiring Rules for safety, design, installation and testing of electrical installation may be met.
The following article provides worked examples of low voltage cable sizing calculations with an average 75 % time saving and $3,366 cable cost saving using
