Replacement rcd for a swift challenger

[Maggie McB]

Hi, first time poster new to caravanning, I tripped the electric in the caravan which has resulted in a rcd trip switch fault, it's not resetting at all, I got an electrician out and they have tested cable , mcbs all fine, can the rcd be changed by itself or is a new power module going to be needed? Many thanks

The Electrician should have been able to sort it for you. The details on the RCD if given to an Electrical wholesaler should be able to supply one. But I would recommend you get a qualified Electrician to fit it for you, (Safety First)

The RCD can indeed be changed. On older caravans, some EDUs were pop-riveted together , so you may need to drill out the pop rivets to gain access . the RCD type is a 25A 30mA type and can be bought from any electrical wholesaler , If you can't get hold of the 25A version a 40A 30mA is OK or even a 60A type ( as it will handle a higher current but still trips at 30mA). You can get them from camper select , CPC Farnell, CEF (City electrical factors) (pennine leisure supplies, but you have to set an account) also the ubiquitous ebay .
I did find it odd that the electrician could 'test' the MCBs without the RCD being ON or taking apart the EDU to get at the MCB terminals. Point to note :- the RCD won't switch on if there is no power to it .
