The electrical system in a caravan should be checked regularly. Because a caravan is constantly on the move it is possible for connections to come loose due to vibration. If the van or camper trailer is pre-owned it should be inspected to ensure that sittings are of the type approved for caravan use.
All safety devices, light switches and power points must be a ‘double pole’ type. Extension leads that connect the van to the outside supply must have a 15amp rating. These leads can be identified by an earth pin that is wider than the other two.
When fitting accessories like shelves or towel rails always consult a caravan repair specialist to prevent drilling into hidden electrical cables. It is also important to be aware of where your switchboard, and associated safety devices, is located.
Maintenance, servicing and upgrades to the electrical system are to be carried out by a “competent person” as defined by each state/territory electrical safety regualtions.
