Youtube electricians

A list of youtube electricians and their various contributions which might assist diyers, and others, who are interested in broadening their knowledge and/or being entertained. It's surprising what can be learned from watching a professional electrician go about his job, but, like anything, the more knowledge you have to start with, the more you get out of it. The list is from David Savery's channel:

SparkyNinja, GSH, John Ward and Joe Robinson Training cover electrical theory

Artisan Electrics, James Beck, Nick Bundy, My Trusted Electrician, CJR, Delroy the Spark, DSS, STF, B.L., Tom Nagy, A&R, Elexcel, LA SparkTV and others provide on-site content.

Channels such as eFixx, Wills Electrical Services and Steve Brindley have tool reviews.

For state-of-the-industry you have e5 and EGTE (electricians guide to everything).

Blup

Got links to all those?

John Ward is good, he is on this forum, however some of the U-tube in fact not only U-tube but channel 4 they make so many errors, and to be frank likely we all cut corners.

However when you see a know comedian like Jerry Clarkson on TV you know it is not serious and it is simple entertainment. However some of the U-tube videos you can think your watching a serious video on how to do, or not to do the task, unlike the forum where likely some one will say some thing daft and then every one points out how daft with U-tube that does not always happen.

So I would not like to list any other than John Ward.

Similar situation on the gas side...and even worse are some of the boiler manufacturer channels....one muppet advocates using the continuity setting to measure resistance

I like watching Thomas Nagy trying to do commercial work

As a domestic installer he seems pretty good, and I certainly wouldn’t swap places with him doing domestic installs in central London!

Obviously it goes without saying that John Ward is the best YouTube electrician

A lot of them say they aren't guides for DIYers.

Wish Nick would post some videos

I’d second Andy here. The most useful videos are posted by trainers. They are posted as additional training and you can see how and where they link to courses.

Some of the ‘here is my day’ videos are entertaining and don’t pretend to be educational. I have bought tools after seeing them used in videos. Last was a ryobi lamp which lights the room rather than a beam. Great in a loft or in a crawl space.

You may need to be carefully there - electricians appear to describe low resistance measurement as 'continuity testing'

Kind Regards, John

That depends on the meter, some of mine include the 200Ω range on continuity and it's a useful facility.

I use a number meters to measure resistance, I don't have all of them, so I would list them as:-
Resistance meter part of the multi meter function.
Resistance meter using at least 200 mA to test with for low ohm readings.
Resistance meter that measures volt drop often part multi meter for testing diodes.
Resistance meter with an audible function better called continuity meter.
Resistance meter using 250, 500, or 1000 volt better names an insulation tester.
Loop impedance meter.
Resistance meter which compares to a know resistance better know as Wheatstone bridge, or a comparator.
The name multimeter is not easy to define, as I have used meters with multi functions that use 200 mA, 500 volt, measure loop impedance, and measure time to test RCD's the one I use most will not measure DC amps, and does not measure amps using leads, I got one of these for my son when he started as not having a wired amp range, only clamp on means it in the main can't be damaged as easy or cause ionisation so far safer.

However trying to say people are wrong is not easy, remember in USA what we call extra low voltage they call low voltage.

However I cut corners from time to time, I am sure we all do for every trade, I remember showing an apprentice how to time a DPA pump on a old landrover, I showed him the right way putting in the setting tool, and also the normal way using a tyre lever and watching colour of exhaust, but with that there was no danger, but with electrics often there is, and copying but missing some thing out can mean person copying gets into trouble. It is too easy to miss showing some vital action.

But they are switching the multimeter to its continuity setting and only listening for the beep
And of course multimeters have different thresholds (and indeed some are presetable).
In the boiler industry we are often looking for no more than an ohm on contact sets.

I remember using a bell and batteries, we called it ringing out the circuit.

A contact resistance of 1 ohm would indicate the contacts were in meed of replacement

From a relay manufacturer's technical information SHEET

Contact resistance: Measured, according to Application Category (Table 4), at the external terminals of the relay. It is a final test value, not necessarily reproducible subsequently. It has little effect on relay reliability for most applications since a typical value would be < 50 mΩ

Me too. We called it (still do) belling out the circuit.

We're not talking about relays though....
We only need to measure the resistance as a guide to contact condition...
In fact most boilers today will operate quite happily with a contact resistance of 100s or even 1000s ohms resistance since they are in a potential divider network feeding into the uController A to D converter.
