i have my 2392 practical coming up.i'm fairly confident of the testing to be done on the board. the problem i'm gonna have is the three certificates to fill in. schedule of tests i'm fine with. schedule and inspections i'm ok with. but the certificate itself i haven't even seen and we've been doing this course for 8 weeks.the idea to this exam is that we've just done a new install and this is the initial verification of the install.
here's what we have.
1)1x16 amp radial circuit with 1 socket.
2)1x6 amp lighting circuit with 2 way 1 lamp.
3)1x40 amp cooker point with 1 socket
4)1x32 amp ring circuit with 4 sockets and 1 spur.
now i make the maximum demand this:
1)40% of 16 amp (as have 32A ring which will be bigger of the 2 final circuits)=6.4A
2)66% of 6 amp =3.96A
3)1st 10A then 30% of remainder so 30% of 30A =9A then add 5A for the socket outlet making the cooker circuit 24A
4)100% of 32A=32A.
i make it 6.4A+3.96A+24A+32A=66.36 amps.
is this correct?
