(4AWG) Ignition 0.5mm2 (20AWG) 0.5mm2 (20AWG) 0.5mm2 (20AWG) iTechworld strongly advises that a properly trained / qualified individual conducts this task. Failure to establish a secure connection could result in a short circuit, potentially leading to fire and property damage. -
Page 9: Wiring
For wire extensions, it is advisable to utilise soldered butt splice connectors. This ensures minimal resistance in the connections. The optimal approach is to crimp both ends of the connector, followed by soldering both sides of the connector. Once the connection is secured, it is crucial to employ heat shrink tubing to protect the connections and prevent any short circuits. -

Page 11: Fuse Specifications
FUSE SPECIFICATIONS FUSE SPECIFICATIONS It is essential to install all recommended fuses in series within the circuit. Bolt-down fuses are the preferred choice as they guarantee a low-resistance connection. In contrast, self-resetting circuit breakers are not recommended as they may trip prematurely due to the heat generated by the current fl owing through the wires. -
