Wiring Unlimited

1. Introduction

In this section:

Welcome to "Wiring unlimited", a book about electrical wiring systems containing batteries, inverters, chargers and inverter/chargers.

With this book, we aim to explain the wiring basics of electrical systems. We will explain the importance of "getting it right" and cover the issues that might result if a system has bad wiring. It also assists electrical installers or users in troubleshooting issues that have arisen from bad wiring so that a correct conclusion can be drawn for the electrical systems they are involved with.

Wiring issues are often a cause of system problems, or they can lead to the underperformance of systems.

For a trouble-free operation of any electrical system, particularly those that contain an inverter/charger and batteries, which are "high-current" devices, it is essential that the system's wiring is done correctly.

This book will help you with "getting it right".

1.1. Safety warnings

Electricity can be dangerous. It can cause harm to persons or property.

It takes a remarkably small amount of current across the human heart to stop it. Due to the natural resistance of the human skin and tissue, this means that a high voltage is required to generate this heart-stopping current, but humans have died from voltages as low as 42 Volts.

Both DC and AC can cause this fatal occurrence. Electrical work should, therefore, always be carried out by a qualified electrician or technician and the local safety guidelines and requirements need to be adhered to.

Warning

IMPORTANT:

  • AC and DC voltages exceeding certain levels are dangerous and harmful.

  • Always use insulated tools when working with electricity and batteries.

  • Do not short-circuit batteries. This can cause fire or explosion.

  • Battery charging can create explosive gasses.

  • Undersized wiring or bad electrical contact can cause a fire.

  • Always refer to the safety warning in the appropriate product manuals.

1.2. Disclaimer

The sole purpose of this document is to aid in understanding the basic principles behind certain electrical concepts. This document is intended as a guide only.

Electrical wiring regulations can differ based on where you are in the world. Your local electrical regulations can vary from the wiring advice given in this document.

You are responsible for always seeking professional advice and instruction from local authorities and/or licensed electricians before undertaking any electrical work.

1.3. Glossary of terms

This book utilises the metric system and all units, and shorthand notations align with the International System of Units (SI). For more information on the International System of Units see this link: https://en.wikipedia.org/wiki/International_System_of_Units
