SAFETY PRECAUTIONS:
1. Make sure your baery has enough voltage to register on the charge controller (8V DC minimum).
2. Make sure you have the right size wire. Wire sizing typically includes 2 consideraons:
A. NEC minimum wire size to avoid overheang the wire, based on insulaon material.
The following is an excerpt from the Naonal Electrical Code . It can be used as a general guideline for
wire sizes. Take note of the materials listed (copper/aluminum) and temperature rang. Many of Cung
Edge Power’s wire is not included in this table because we use very special, high temperature/current rat-
ed 200°C silicone insulated nned copper wire.
