A slight rant. Having just finished a spate of commercial EICRs I really can't understand why we tolerate these wretched things:
1 - I now expect there not to be a continuous CPC on emergency lighting circuits. The odds of someone losing the fight with the spring-loaded twin-terminal and earth-sleeving with at least one of the fittings since the last EICR are seriously high.
2 - The more ridiculous the location is, e.g. 5m up in the air, the more likely either:
a) the connections won't be properly made OR
b) the entire connector block will be broken off the PCB as someone presses too hard trying to connect them properly:
(this is how I found it)
3 - When you replace a unit, it will work for either years or just long enough for you to leave site. If it's sited 5m up in the air where you can't rest a ladder, it is guaranteed to fail within 24 hours. This one straight from the merchants lasted 4 hours:
4 - The design WILL change every 10 minutes, so 99% of the time the entire unit will need changing.
5 - About 50% of test-key switches might as well not be there as they have been fitted by a muppet and just replicate the circuit breaker. It's a pleasant surprise when one actually does what it's supposed to do and only isolates emergency lighting. The test switch I operated today killed the intake room normal lights (plunging my assistant into darkness in front of an open CU,) the top three floors staircase lighting, and the TV amplifier and Satellite receiver boxes in the attic. (It was an excellent way of quickly simultaneously meeting about 25 residents)
I'm probably asking for the impossible, but I'd love to hear of a product that:
a) has screw terminals which make (mostly) one handed connection possible, allows connection quality to be visually confirmed, and as a bonus testing can be done with GS38 tips still on.
b) keeps the design consistent long enough to simply change part of it after a failure
c) has an above average chance of working out of the box for more than 24 hours.
Any tips gratefully accepted!
