Hi guys,
Sat my AM2 today and yesterday overall I think it went well all bar one quite bad mistake.
When running my cables in (singles) from the CCU to the DOL starter I didn't bring a Neatural.
I completed my dead test on the circuit using on each phase to Earth and obtained my highest R1 + R2...
Hi everyone. I sat my AM2 last week and passed everything except the fault finding.
They just tell u pass or fail not what u got right or wrong etc. I struggled on the faults I'll explain below. I know the faults will be different next time but would still like to know how to approach these...
Something I have found nobody has experienced before, just me unfortunately, but I thought I'd try you guys for one last fault finding. Thank you in advance.
Over some years I have had to keep replacing the magnetic contacts on my outbuilding where I have the Accenta Gen4 system setup.
Issue...
Tested one of our generators this morning, only about 76KW engine set. Started up fine, took the load of the building fine, connected a load bank, fine. Voltage readings all 240ish, temperature as expected, oil temperature as expected, coolant temperature as expected. 1.5hours later. Chug chug...
Evening chaps,
A few months ago I installed 6 x 30w led flood lights around a commercial building, I wired them in series from a ip66 box with a night and day sensor and a contactor, I went to each light via a smaller ip66 box in 2.5 sy cable, everything tested OK so off I went.
I received a...
Two years ago I installed some garden lighting, using u/g SWA to Wiska boxes, then 3-core 0.75mm rubber flex downleads from each LED fitting.
This week the 30mA RCBO kept tripping. I assumed a luminaire fault, or moisture in a Wiska box, but no. It was leakage across all three cores of one 10m...
Hi all.
Can someone point me in the right direction for the current regulations on control panel isolation for machinery (industrial) if possible please?
An issue arose with a machine trapped key system failing, allowing an individual to remove the key, but the machine staying live and...
Normally the Landis & Gyr E110 single rate meters are pretty much bullet proof, but I've had two fail on the same installation in less than a month. I'm looking for any clues as to the cause.
Installation is a typical 4kW solar PV system. About a month ago, the FIT meter just died (display...
Interersted to hear others experience of this. Have had a spate of replacements recently. Most common failure has been Power One, but also had a couple of Sunny Boys.
If out of warranty, SMA will supply a refurbished unit for around €425.00 with a one year warranty. I have been using Sofar...
I have a 2008 VW Passat Tdi which has been no issues to me during the last six years, of late I have had a few what i believe erroneous fault codes, parking brake issue (The known parking brake issue has already been dealt with) and more recently a DSG fault code. I say they may be erroneous as...
Hi,
What do people consider is an acceptable failure level for LED bulbs?
I have two examples, both from TLC "LEDLite" home brand lights.
1st, I fitted 6 of their 8W filament LED bulbs with 2 years guarantee in my parents house, and 3 have failed within the first year. (50% failure in...

The lights failed badly
Struggling to find lights that will fit the cutout 75mm or cover it surface mounted which are steam room approved

any suggestions for ideally a plug in device that connects wirelessly to a battery operated bell in house should the sockets in outhouse (freezer full of stuff go off).? Outhouse is on own rcbo so customer unaware of power loss untill its too late :/
Anyone heard of or had problems with these? I've had a couple fail in the past that got very hot and a bit melty but always thought it was a poor connection by the spark we used at the time.
Working with another company now who have had a couple fail recently also so am very concerned that...
Hello
I attended a customers property today to check on a fault with some latern courtyard lamps. There are 4 lamps and the centre 2 are not working. The customer had replaced the bulbs himself but there was no joy.
As a first port of call I swapped the 2 working bulbs from the outer fittings...
Hi guys, be kind, I used to be in the trainee section and need some advice regarding emergency lighting and common points / modes of failure which is a relatively new area for me. Two situations.
I have some work in a commercial setting, and have recently noticed that one of the non-maintained...
Thought i would post that i failed my 309 written exam.
As did half the class. College tutor had a go at us and said he covered everything.
But what i think he failed to realise that when you have the brainy lads talking all the way through any explanation how is a dumbass like me going to...
I was wondering, I'm not at work so can't ask one of the blokes, but I have been looking in auto change over switches, on supply loss how are the contactors switched as obviously the supply has been lost. Is this done off the generator batteries/sustained supply (UPS) ? Please I'm only an...
