In this video I demonstrate using a Megger MFT to carryout the continuity of the cpc, polarity and insulation resistance tests for this smoke detector circuit. This circuit is wired in FP200 and MICC cable via a fuse connection unit. This circuit is similar to one in unit 107 of the City and Guild. Videos are training aids for City and Guilds (C and G) and EAL courses Level 1, 2 and 3.
You can follow me day by day on Facebook, Instagram and Twitter lookout for "GSH Electrical.
