I have just installed a complete new kitchen including double fan oven (5.4kw), hob (6.4kw), griddle (1.4kw), steam oven (1.5kw), plate warmer (1kw), microwave (.9kw), fridge and freezer.
ONE. 6m of 10mm cable run from a 40 amp RCBO (at the moment) in the CU to a 60 amp 3 terminal junction box. From the junction box I have a further 5m of 10mm cable running to a 45amp cooker switch and socket. The switch operates the double oven via 6mm cable and the socket has the microwave plugged into it (via a 13amp fused plug). Also wired into the junction box, is the hob via the supplied cable (six core heatproof flex).
TWO. The steam oven, plate warmer, fridge and freezer are wired in a 32 amp (RCBO) ring each fed from a 13 amp fused spur.
THREE. The griddle, gas hob ignition, waterproof TV (12v DC via transformer) and 3 double gang wall sockets are also wired in a 32 amp (RCBO) ring.
I have completed all of the wiring, nothing grouped, all clipped etc.
I have fitted and wired the double oven (not the hob), BUT! When the oven reaches about 180 degrees, the RCBO trips. In addition, when the grill is turned on, the RCBO trips after about 2-3 minutes. I can only assume that the issue is the length of cable used as I calculate that the oven is 23.48 amps! As the total amps will equate to 51.30 when the hob is wired too, would a 50 amp RCBO be OK to replace the 40 amp RCBO and would it resolve the tripping problem?
THANKS!
