The objective of this book is to explain the engineering principles behind best practice electrical panel building, including:
- Why should AC and DC wiring be kept separate?
- Why should different voltage wires cross at 90 degree angles?
- Why should wires never run parallel in the same trunking?
- Why should there be empty space around components and how much empty space should be allowed?
- How can heat dissipation requirements be calculated and can the required airflow be calculated?
- How will a fan improve air flow?
- How can panels be wired to ensure equipment is protected and able to be isolated for fault finding?
- Why should all ground wires should originate from a single point?
- What is the international standard for cable and wire marking?
- Is there a naming convention for wires based on their function?
- How can water and other contaminants be excluded from the enclosure? (e.g. positive pressure systems)
- When should shielded cable be used?
- When should twisted pair cables be used?
- How can temperature be managed?
- How can humidity be managed?
- How tight should terminals be tightened?
- What is the bending radius of wires?
- Why is there a minimum bending radius?
- What sort of lights should be used?
- What about drain holes and air vents?
