Your caravan is equipped with a 16amp RCD combo breaker. This is both a Residual Current Device and a standard over-current circuit breaker. This is in place to shut the power down in the case of a fault which could lead to shock as well as if too much power is used within the van.
There are a number of steps to take if your mains power is shutting off.
Before looking towards potential faults, think about the appliances that were being used when the power shut off. Due to the limitations of the power coming into the van, it is limited at 16 amps meaning a total of 3840 watts can be used in the van before the power is cut off. This includes things such as Air Conditioner, Fridges, Hot Water Services, Microwaves, etc.
A table is provided below as a reference for some of the average draws found in a van. If at any time you exceed 3840w in total, you will lose power and have to reset the breaker.
| 3-way Fridge | 300w-400w |
| Air Con | 1600w |
| Hot Water | 1450w |
| Kettle | 1600w-2400w |
| Toaster | 2000w-2400w |
| Battery Charger | up to 450w |
| Microwave | 1200w-1400w* |
*Microwave power is the input not rated output. Most 800-900w rated microwaves use between 1100w and 1400w. Check the manual of your device for the consumption rating.
If power usage does not appear to be a factor, proceed with the following checks-
- If your "shore" or "pole" RCD is tripping, try using another lead as well as another pole with your lead and a different lead again. Most people will be glad to help a fellow caravanner with the use of their lead to test if you don't have a spare on hand. If the issue goes away when a different lead is used or a separate pole is used, this will be the likely cause of the issue. Cease using the lead immediately and either replace it or have it checked by an electrician. If the issue appears to be the pole cease use immediately and contact park management. If the issue is still present, continue with the next section.
- If the RCD on the van is tripping or the problem persists after the above checks, begin by unplugging all appliances in the van. Unplug ALL appliances, even those not in use, including your Battery Management System, Phone-chargers, Microwaves, Fridges, Hot Water Units, Satellite systems, TV's, Air Conditioners, etc. Begin with the isolation switches for these items, if present, in the "off" position as well. These switches can be found in the controls area of your van and will normally be labelled clearly. Check to see if the breaker trips while everything is shut down and disconnected. Contact your dealer or us immediately if the issue is still present.
- Turn the isolation switches for the fridge, stove, AC and HWS on. If the breaker trips, contact us immediately.
- If the power is not tripping, it means the issue is most likely in one of the appliances. Try plugging in each appliance one by one. If the breaker trips while doing this, try plugging into a different outlet or run the external lead through a window. If the power trips, cease using the appliance immediately and contact your dealer.
