Excellent all.

First off thank you Spencer for sharing your wealth of knowledge. Just thinking out loud if we have to produce a design to use either an internal core or a separate cpc instead of the armouring due to an environmental condition or some other reason, but the armouring is glanded into a metal enclosure surely the armouring would still count towards the sum of the cpc due to parallel paths and have the same emc/reactance affects. The only way i can see you can truly achieve seperation and the armourings not forming part of the earth path would be to isolate and insulate the armours at one end, with the other connected to earth, then you truly have a separate cpc. However you still may have parallel paths through other metal components but the emc issue will not have the same effects due to the armouring path being broken. Am i over thinking this or should installation practices alter when this condition is present? Also regarding swa cables buired direct and the armourings needing to be the CPC, should more emphasis be made in guidance notes regarding this as i suspect this is one regulation that is often overlooked? Achieving this can be a challenge with some equipment such as street furniture, ground mount EV chargers etc as there is generally no place to make a gland off too. This often leads to installers using an internal cpc and taping up the armourings or fitting a gland with cpc link but the gland and cable float in the air so are technically unsupported with no room for the electrician to retro fit a bracket of sorts for the gland to be secured too.

Daft questions for clarity PNB, with PNB any installation requirements that are specific to PME don't apply? so for example installing an EV charger on a PNB installation would the requirements for PEN conductors not be a factor/requirement?

Do conductors in parallel not have to be the same CSA, same material etc even for a circuit protective conductor (2 x cpc’s in parallel)?

Cheers

Well done Darren. Eca are levelling up. 🫡👍

I don’t think the Fuuse presenter realised that Part L now requires all lighting circuits to be separately metered.

Thanks for this video Darren 👍

Fantastic video Darren. Thank you!!

Need to make this CPD

Great vid, inspiring voices.

Question: Is a test switch required for self-test emergency luminaires

Hi going to listen to this later… meanwhile back to work

Very interesting and informative Wyn. This just highlights the amount of work that needs to be done for Wales to meet their targets and the colleges important role to play in delivery.

*Promo sm*

Love this, any chance you can do one for emergency lighting certificate

Is the load end of fused spur considered as a point?

Another good presentation from the ECA tech team

Awesome

Philips Master LED dimmer bulbs are down to 3.4w. Their latest is down to 2.4w (40w equivalent). Will be quite off if our bulbs are reducing energy use but smart switches can’t…

? ???????

Great video 👍

We apologise for the technical glitches in the introductory part of the recording. This is resolved from 10:00 onwards and does not affect the core presentation. We hope you enjoy this ECA Learning Zone replay, and do make sure to leave your questions in the comments!

1) By reflecting away 30% of ISR the albedo, which would not exist w/o the atmosphere, makes the earth cooler than it would be without the atmosphere like that reflective panel set on the dash. Remove the atmosphere/GHGs and the earth becomes much like the moon, a barren rock with a 0.1 albedo, 20% more kJ/h, hot^3 on the lit side, cold^3 on the dark. Nikolov, Kramm (U of AK) and UCLA Diviner mission all tacitly agree. 2) the GHG up/down welling, “trapping”/”back” radiating/delaying/intercepting, 100 % efficient, perpetual warming loop requires "extra" energy which according to RGHE theory it gets from 3) the terrestrial surface radiating that "extra" energy as a near ideal .95 emissivity black body which 4) it cannot do because of the non-radiative heat transfer processes of the contiguous atmospheric molecules. 1+2+3+4 = 0 Greenhouse Effect + 0 Greenhouse gas warming + 0 man caused climate change. All science backed up by experiment, the gold standard of classical science. www.linkedin.com/posts/nicholas-schroeder-55934820_climatechange-greenhouse-co2-activity-6749812735246254080-bc6K Version 1.0 252421 ECA services

Hi mate

Good advice and short enough that people will watch it. Well presented and simple, I love it. Remember as well to think about all normal H&S controls such as safe manual handling, isolate and lock off etc.Stay safe and go home healthy.

Daniel McBrearty As a responsive repairs electrical company we can't replace our overalls after every call-out. Does anyone have any suggestions? The electricians wear uniforms.

Yes Very good and nicely done, shame about the cups of tea, still always better safe then sorry.

Good effort guys, useful information for everyone involved. Stay safe...

Dans the man 👌👍

Fans the man 👍

Cheers Luke, as always a good explanation.

Thanks for having me to be able to be part of this podcast. I hope it helps some business owners 👍

would be even more useful if we could see the slides

finally some useful information on this channel. would be good if we could see the screen above though

"there is nothing significant we need to draw out of this chapter" - That'll be £90 for new books and £400 for retraining then please

haha, "it doesn't change how we do things, its just a change of word" ...That'll be £90 for a new book then please

Well done Conor - we're proud of you. From The Team at Darke & Taylor :-)

Very noble.

I really like the colour of the new book and ... well not much else to be honest

The bottom line is that electricians are going to have to spend a small fortune on yet more training and literature if they want to stay part P registered.

Why are these constant amendments necessary? Honestly! What specific events have occured since the introduction of amendment 3 to justify the pending 18th edition?.... That's assuming a 4th amendment doesn't squeeze in in the meantime! A few more quid to be made...

The thing is, the regulations, despite all the changes in the last few years to tighten up, are STILL only advisory!
