ok lets think about this, so if you rewire into a ring, and plug these appliances in, do you think it will stop tripping the 32 amp 'b; breaker?

 

[domestic spark]

what your saying is as its already on a 32a breaker, it would need approx 40a to trip.

 

[domestic spark]

which is greater than 3 appliances plugged in

MCB tripping as 2.5 spured from ring feeds, 2 or more appliances, kettle toaster w/m, one single 2.5 max 27a depending on installation methords so at best, so this side of kitchen is clearly overloaded?? thats my logic?

 

[domestic spark]

for MCB tripping

 

[domestic spark]

but no i dont want to do the job and for the problem to still occur!

 

[Guest 004]

lets not get confused with cable ratings for the minute, as you have done an IR test, the cable has stood the test of the current of these machines, I trust you got >200M

 

[domestic spark]

>500 flukes

 

[Guest 004]

so the cable is sound, and not breaking down, although insufficient to BS7671, the cable will not cause the mcb to trip right?

 

[domestic spark]

so im on the wrong lines, and if i rewire all correctly, im going to look a fool! as i wouldnt have solved any problems?

2 new rings might sort it, or he's got a duff cooker, along with the duff hob

 

[domestic spark]

let me explain, cooker 6mm radial, 32 type b MCB, Hager.

from cooker switch oven is connected to outlet, from outlet a s/so with hob plugged in (plugtop) this is what was tripping, RCD, knocking out all power to DB. dissconnected that. problem solved. he told me, was a bit silly cleaning it soaked it and hadnt worked since then. (TRIP)



APPLIANCES on KITCHEN RING, toaster, kettle, t/d, w/m, fridge.

when too much is plugged in over the "spured side" thats when MCB tripps

 

[Guest 004]

do a load test on each appliance, one at a time.

 

[domestic spark]

what plug each appliance in on there own? and see if one causes ring to trip

 

[Guest 004]

Do you not have a clamp meter?
Do you remember the principles of Kirchoff's current law?

 

[domestic spark]

i dont have a clamp meter no.

Do you remember the principles of Kirchoff's current law?

never tought it

 

[Guest 004]

ok, if you change the circuit to a ring, you will still have the same amount of current flowing through the MCB, regardless of spurs etc, with everything plugged in, so the MCB will still trip.

 

[domestic spark]

yes but load will be equally shared, no overload to cables
