Clicking noise coming from habitation fuse box

[nomad2022]

Hello all I have a clicking noise coming from my Motorhome habitation area fuse box - 2008 Bessacarr e460 everything seems to be working fine and all fuses are ok - has happened before and stopped of its own accord but has now been going on for over 2 days - clicking every 8 seconds or so - has anyone had similar or does anyone know what might be causing it? Any help advise greatly appreciated

The (Nordelettronica ?) fuse box / PDU has many relays within it and it could be a faulty relay , you could try removing one fuse at a time and see if this locates the possible source of the clicking if the noise stops.
