Autumn is now here, it's that time of year where the clocks go back and lighting control moves forward. A time when UK customers with gardens want to light up their outdoor spaces earlier in the evenings; meaning they'll be looking for new lighting and a reliable method of wireless switching...
Having to wire around a messed up output for a month or so. Some sort of program corruption is keeping the central lubrication system from operating at the correct intervals. I've never had to do this so I'm not sure which sort of On Delay/Off Delay setup could be used. But I need a 1 minute...

Hi,
I purchased a Time twin strand bell cable with a rating of 12-30V, 2A, low voltage, not for mains use.
I wish to use this for installing our new Ring wired doorbell. We don't have an existing doorbell wired setup so it would need to conform to a DIN rail transformer specification of 24Vdc...
This is quite lengthy so get comfy...
I had a bizarre call out relating to a job I attended about five years ago. The situation was they were getting regular short term low voltages across all phases, only a few seconds, but enough to make lights flicker.
In the intervening years they had done...
I've scoured the internet for what these do and am coming up short on finding information.
What are these for? (ie what specific problem are they trying to solve) and why do they need to be time delayed?
Thanks in advance

On a TT system the rcd must operate withing 0.2 seconds for many circuits. Why when we test rcd's does it not say 300ms for TN systems or 200 ms for TT systems?
We all know how to and why we get the 1/4 value, but to what, if anything do we add to that figure and into what box on the cert does it go, depends on who you ask/assessor is apparently,

Hi
A professional electrician installed power to an outside greenhouse about 6-7 years ago. The supply has very recently developed a recent RCD tripping fault. By process of elimination, the overwhelmingly likely place for the fault is a N-E leak in a Prysmian Resin Cable Joints between two SWA...
