MCB Problem - Possibly needs a larger rated MCB?

I’ve got to agree with E54, why degrade a good system to accommodate incompetent installation and testing?

You would have been closer to tears if you had to rip it out and start again like I did. I'm just sooooo glad he put laminate floors in every upstairs room too. Made it so much easier.

I've just seen the op's new member intro. Avionics technician, that will explain the detailed question he asked. Not as wet behind the ears as we all thought.

My point is only that I'm not sure ring finals are a good system anymore....While I still install rings by default,I wish radials were standard practice in the uk,rather than rings.

radial 16amp breaker type b, ring 32amp breaker type b. If it is a type b try chaning MCB for type c. does the MCB trip or does the RCD trip?

I agree with flyingsparks, this is not a good resolution,
As he said, and also I doubt the circuit would meet the lower Zs for a type c to disconnect as required

hi how ya doin mate well for a start tumble dryers pull savage current remember its 4.3 amps a kilo watt try a 20 or 25 amp mcb and buy a good ammeter it will tell you how much current is being pulled , when im first fixing i always runs rings especially in a kitchen where most of the power is going in a house and rings are better for testing pre and post connection
