Hi Guys any of the older generation had this problem with their grading.
I'm a time served Approved, or thought I was.
In the early 1980's I got my approved card from the SJIB.
During the last 23years I've worked in the Security Alarm industry.
I was made redundant dec2011, and am chasing the...
I attended an inspection of an office and workshop last week. There were quite a few issues, but I was intrigued by the issues depcited in the photos. They had 4, 3phase machines (saw, drill, grinder, plane) which were wired into only 2 isolators (and 2 circuit breakers). they did have...
Right as you probably know all the JIB titles have changed, again.
Part of me likes the masses of definitions, but my question relates to what do they mean?
One in particular.
Provisional electrician.
Can a provisional spark work on site unsupervised, or does he need to be watched like a...
Hi all, we have just completed our 1st install ready for our MCS. The DC cable is a little to short, do you know if it is ok do add a connector to extend the cable? Would this be acceptable to pass the MCS accreditation?
Many Thanks
Hi All, I was called to an RCD tripping problem tonight and I have found the cause which was a intermittent problem on a lighting rig.
My issue is that during my testing I did a slope test of the 100mA RCD protecting the main board. It was tripping at 65mA, my question is what value is...

The issue I had was they were pushing for an install with scaffolding going up on the day I came...
(Please be gentle, its only my second install)
I've just installed 10 RECs with an SB2500HF and i'm trying to commission for handover. I've measured the voltage of each panel, which was correct, and my Voc today was about 300V. However, I'm only measuring Isc of 0.4A. The install is a top row...

Had a bit of a scrap on site yesterday with the site foreman after the plumber decided to go drilling underfloor heating pipes about 20mm away from my main rise of CU cables - and there's a lot of them!
I wanted to, and can (still) see no good reason not to, move the plumbing feed over one...
So a few weeks back I get called out to a guy who's RCD won't set. He's just returned from holiday to find this so not much idea from him when the initial fault occured. To be honest, I was expecting to turn up and find that he needs a new kettle as this is in my experience almost always the...

Hi,
Hi all,
I am doing the 2391 course at the moment and I'd like to know the best solutions to a high Zs value of a circuit which does not meet BS7671 requirements. This high reading doesn't come from any damage or loose connection but due to a design mistake. The circuit is protected by a...
I want to level 3 as i've done the 2330 level 2 and am i right in thinking this is the last year to do it before it's all rolled in? think i might have been too late umming and ahhing as i've had to weigh it up with work and am now having serious regrets as it feels like a waste. what are the...
i can do all calcs for designing a circuit as in Ib,In ,It etc. heres my wonder. how can you work out whats the max distance you can run a circuit without being caught on VD and max Zs. easy way maybe im missing.
i know IxR=V and you can just keep rechecking till you get within values.
or...
We have a 29.76kw system of REC 240w panels. Feeding 2 x SMA 1500TRL Inverters.
