Potential Electrical Issues in Your Motor Caravan

At CCCampers, your safety is our priority. We understand that electrical problems can be a concern for motor caravan owners. Here's some information to help you identify potential issues and understand the importance of addressing them:

Have you noticed any of these:

  • Frequently tripped fuses or Residual Current Circuit Breaker (RCCB)?
  • Electrical appliances not functioning properly?
  • A burning smell or signs of overheating near electrical components?
  • Earth Bond resistance is too high?

These could be signs of electrical problems in your motor caravan.

What could be causing the issue?

  • Failed RCCB Trip Test: This safety device is designed to trip and cut power in case of a ground fault (leakage current). If it fails a test, it might not protect you from electrical shock.
  • Outdated Single Pole MCBs: While previously common, current safety standards recommend using double pole MCBs for most caravan circuits. Double pole MCBs offer better protection by disconnecting both live and neutral wires during a fault.
  • Poor Consumer Unit Location: If your consumer unit (fuse box) is in a very poor state, damaged, or located in an unsuitable place (e.g., damp or exposed), it can pose a safety risk and affect the overall electrical system's functionality.

Introducing the PowerPart Prewired Consumer Unit: A Cost-Effective Upgrade

If you're experiencing electrical issues or your consumer unit needs replacing, consider the PowerPart Prewired Standard Mains Consumer Unit. This pre-wired unit offers several benefits:

  • Safety and Reliability: It comes equipped with a Type A 25 amp RCCB for improved ground fault protection and a 16 amp MCB for circuit overload protection, meeting current safety standards.
  • Convenience: The plug-and-play connection to the mains inlet (with a 2000mm cable) simplifies installation compared to a traditional consumer unit.
  • Versatility: It includes four pre-wired socket outlets on a dedicated 16 amp circuit (300mm in length), providing readily available power points.
  • Cost-Effectiveness: While an initial investment, a pre-wired unit can be a cost-effective solution in the long run. It saves on time and potential complications associated with separate component selection and wiring during installation.

Important Note:

Do not attempt electrical repairs yourself. Electrical work should only be performed by a qualified caravan electrician.

What should you do?

  1. Contact a qualified caravan electrician to diagnose the problem. They can assess your current consumer unit, identify any electrical faults, and recommend the best course of action.
  2. Discuss the PowerPart Prewired Consumer Unit as a potential solution, considering its safety features, convenience, and cost-effectiveness for your situation.


Regular electrical inspections by a qualified professional can help identify potential problems before they cause a trip or more serious issues.

Remember: Safety first! By addressing electrical problems promptly and using qualified professionals for repairs and upgrades, you can ensure a safe and enjoyable experience on your Motor Caravan adventures.
