Wiring standards
Before you start wiring the panel we suggest that you follow a few wiring standards:

All wires and connectors will be identified by a colour coded heat-shrink tag or label,

Wiring insulation will be stripped back 4mm for all connectors,

All wires will be crimped into the appropriate connectors using a crimping tool,

No more than 2 wires will be crimped into any one connector.
Heat shrink tubing should be cut into short lengths (about 2 or 3mm) and used for tagging
each electrical connector or wire in the following manner:

Red = positive

Black = negative (earth)

White = signal
Cut about 20 of each colour to start with and cut more as needed.
Put a strip of masking tape along the bottom rear of the panel under the switches and circuit
breakers and label each one – this will save you having to keep lifting the panel to read the
labels on the front and that will make the wiring a little bit easier.
Wiring the panel
This is a one-wire-at-a-time process that cannot be rushed.
The objective is to use lengths of wire that can later be zip-tied together to form a tidy wiring
loom. The
before and after photos below show how factory wiring is arranged into a loom:
