Ah, the true GG! I can kinda see where you're coming from Tony. On the other hand, I find it good for guys to tell us about faults they have found and how....it all adds to my/our knowledge.
Now, If only PEG would tell us about the mft that lets him do the trick he described.....

If I had to rely on advice from here for fault finding I’d have taken half (what’s left) of British industry apart trying to find a fault.

I couldn’t possibly go in to a customers home and start blundering about guessing what a fault may be based on information from here. I’d end up looking a complete chump. The customer would have no faith in my ability and would soon be telling their friends and acquaintances I was a total waste of time and money. Added to which I just couldn’t bear to be compared to a Electrical Trainee.
 
Which MFT were you using PEG?
Hi dude,sorry for delay,just got back from sunny Cumbria with trailer load of logs,venison and a dish-washer (long story...) Anywho,tester was a 1720,buzzer threshold can be altered on both IR and Continuity. Not certain,but i think on IR,it is adjustable from 0.5 to 500 Meg,and on continuity,0.5 to 100 Ohms.Buzzer can be enabled on both tests. So,basically,if intermittent fault,but some kind of IR value,then leave locked on IR test,if a "Short" (dislike that cover-all phrase:icon12:) then switch to continuity,and set threshold accordingly. Obviously,assessment of what may work best,can ONLY be determined by the man on the ground,and,alluding slightly to Tonys' critique,a method/list/order of tasks can work well for one,but may not "export" with success...:conehead: To be brutally honest,some of my methods,on differing areas of fault finding border on the eccentric.But they have served me very well.If,however,i discovered,a local college was using some of them in their teaching methods,i would expect them to be reported asap! :icon12:

Your earlier post reminded me that I was going to order an ordinary continuity buzzer. My AVI has a continuity buzz, but I could do with something louder that's easy to leave clipped to a cable while I prod switches, etc.

I'm planning to get a Martindale TEK404, as it has build in protection against accidental use on live circuits. Anyone here use one, and is it any good?

I have twice went to customers who's Rcds had tripped and wouldn't reset only to find they hadn't pushed them down fully then up to reset them. Think they were Hager. First time I didn't ask this on the phone so didn't charge. The second I did make it clear on the phone how to reset it so they had to pay for me to switch the Rcd back on. There was also no follow up calls

Ok Tony, fair enough, we'll just have to agree to disagree. You are putting a particular spin on your reply. Whilst I totally agree that no one should be selling their services if they don't have appropriate skills and knowledge, quite simply none of us know everything, and if we can share experience and good practice here, then we are all winners.

MK Sentry units were (down to reset and up to close) like that until a few years back, not Hager as far as I am aware. The current MK Sentry Consumer Units are diabolical.

Whichever way you want to spin it I have to agree with Tony I don't think the internet is the place to be learning your trade while charging people for the experience of employing you.

It's a bit like selling yourself as a bathroom fitter then going into B&Q and picking up a handful of their how to guides to learn how to do it

The bottom line is, a Electrical Trainee won’t have had the time needed to learn fault finding techniques.

It’s something we put a lot of time and effort in to teaching our apprentices. To the point of sabotaging a plant to let them take charge and find the fault on their own. Out of their time they would need to be able to get something running quickly, downtime at £XXXX’s per minute adds a bit of urgency. Only a structured testing method will achieve that.
