In this video me and Marcus look at dead test number 2 in BS7671. In the test sequence this is "testing continuity of ring final circuit conductors, including protective conductors". We go through all 3 stages recording the results and we show the calculation for R1 + RN and R1 + R2 from r1, rn and r2 end to end readings. We prove the circuit is wired as a ring final circuit sometimes called a ring main or socket circuit. After proving the circuit is wired as a ring and the polarity of the sockets and record the results on the testing paperwork. How to carry out a figure of 8 test on a ring final circuit (sometimes call a ring main circuit) == 🕐 Time Stamps - Cut to the action 🕕 == 00:00 - Ring circuit test 00:09 - Continuity of a ring final circuit 00:51 - Stage 1 - end to end test - r1, rn, r2 in ohms 02:19 - CPC r2 is 1.5 mm2 proving 1.67 times greater than r1 and rn 03:49 - Stage 2 - opposite line to opposite neutral (figure of 8) 04:20 - Calculations for R1 + Rn 05:05 - Testing at our fuse connection unit on our ring final circuit 06:16 - Testing at every socket outlet during stage 2 07:47 - Contact cleaner to improve the electrical connection 08:55 - Stage 3 - opposite line to opposite CPC (figure of 8) 09:05 - Calculations for R1 + Rn 09:30 - Testing at our fuse connection unit on our ring final circuit 09:54 - Visual polarity of the fuse connection unit (fuse spur) 10:41 - Testing at every socket outlet during stage 3 12:45 - Completing the test paperwork for our ring final circuit test Videos are training aids for City and Guilds (C and G) and EAL courses Level 1, 2, 3 plus AM2, AM2S and AM2E.
