Amps Posted December 6, 2011 Posted December 6, 2011 4. CIRCUIT RESISTANCE. Pass / Fail. Yes / No. Check resistance against records Check circuits clear of earth faults You check every circuit resistance with a meter or if possible resistance given by the panel? What if the system has 50+ ccts? earth faults?
Able Alarm Posted December 6, 2011 Posted December 6, 2011 i an lucky that 85 percent of customers are domestic, other 15 percent commercial with under 30 devices. Yes i test all Ccts. my customers pay me well for my services and i am happy to get the work. i dont have to rush and its very no so often i have to return between visits. My passing comment to customers is "hope not to see you for 12 months" but there all no that i will be there if needed. AbleAlarmMan Able Alarm Ltd

Some of our jobs can have 12 or more PSU's to check, with 2 eight zone expanders in each PSU. There is no space on your forms for more than one PSU.
Able Alarm Posted December 6, 2011 Posted December 6, 2011 I developed this form for the size of my system but there is no reason additional sheets for larger systems couldnt be used AbleAlarmMan Able Alarm Ltd
antinode Posted December 6, 2011 Posted December 6, 2011 Have you ever actually found any high resistances/shorts to earth or other cable faults through doing these readings on a service? Not having a go, just curious as to how other people work. I personally don't take circuit resistances on a routine service visit unless there is a good reason to (recent false alarm etc). Most of our jobs are FSL wired, so it would require removal of resistors to get a true resistance of the cable. Way too much faffing in my opinion... Trade Member

MrHappy Posted December 7, 2011 Posted December 7, 2011 when we where doubled poled all circuits where measured every visit, the advent of employess made us stop doing this as they caused more problems than they prevented. Mr Veritas God
