There are several international Standards (AS/NZS, BS and IEC) which cover requirements for protection coordination of low voltage electrical systems and this article provides a summary of those as a reference.
Download the attached PDF report template and use it for your solar connection applications.
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 neutral conductor is connected to the neutral point of a system and is intended to carry current under normal conditions. The neutral conductor is
Voltage rise can occur in solar PV systems on the AC side between the power inverters and network connection point. Voltage rise calculations are no different to those for voltage drop.
Accurately calculating voltage drop results in lower voltage drops which leads to smaller cable sizes and saves money.
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 rules are based on Australian and New Zealand rules and the conditions. Low Voltage AC installations Section 3.6 in AS/NZS 3000:2018 covers the
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
