7.1 12V Power Cable Wire Upgrade Service - Undersized Wiring Detected

We’ve identified that the existing wiring used for key 12V systems—such as the split charge relay, 12V fridge, or inverter—is under-rated and may be causing issues due to long cable runs.

When cables are too thin for the length they run, they suffer from voltage drop, meaning your equipment doesn’t receive the power it needs. This is known as long run power drop, and it can result in:

Poor charging performance from the alternator to the leisure battery

Fridges not cooling properly or struggling to run efficiently

Inverters cutting out or underperforming under load

Overheating of cables, increasing the risk of damage or fire

Our Cable Upgrade Service Includes:

Full inspection of cable runs and current demands

Removal of undersized or unsafe wiring

Installation of correctly rated heavy-duty cables, matched for both current and distance

Professional routing, protection, and termination

System voltage and load testing to confirm safe operation

Benefits of Upgrading:

Reliable power delivery across all 12V systems

Maximised performance from your fridge, inverter, and charging system

Reduced risk of voltage loss and heat build-up

Improved safety and compliance with electrical best practices
