content: The one I cringe at is that in the USA, a marine float is pronounced something like "Beuiuiy." They even audibly struggle to say it like that. One lecturer actually did that a couple of times and then switched to the more sensible 'Boy' pronunciation.If they have to pronounce everything exactly as it's spelled, I dread to think what these guys would make out of French.Though, a really silly one they do here is to pronounce the manufacturer Braun as 'Brawn.' It's the German spelling of the colour brown, and pronounced exactly as we do.

content: I only do electrical work when everyone is out. It’s safer for me then.My family members are resourceful enough to find the breaker and turn it back on and disassociated from reality enough that they wouldn’t hear the warning I gave them not to touch anything.My electrician I was using, who I recently fired, usually didn’t even switch off the right breakers before the event.

content: Quote from: IanB on May 13, 2018, 04:15:04 amI don't think he is safe enough, he should use silicone gloves, retest the presence of voltage with 2 or 3 more multimeters just in case, activate and secure all disconnectors and earthing switches in the Medium Voltage substation that feed his area (using padlocks of course), earth all surrounding aerial power lines in case a lighting strikes and have an ambulance ready outside in case anything happens.

content: I recently discovered that in my new house the different circuits are used randomly. There's even a mix of sockets on the downstairs and upstairs circuits within the same room.My only paranoid safety squirrel practice is that I short out the live and neutral with a screwdriver (insulated handle) as a final double-check. You get an audible and visible warning if you've messed up.

(Extensive remodels over the years left us with about 8 different boxes and we'd so far come up empty.)Shorting across the lines a few times, I made impressive sparks and put large weld marks on the screwdriver, but couldn't get the thing to trip. Later investigation revealed that the light (and several sockets) were wired directly to the main (200A) breakers.

content: I have a circuit breaker tracer and it works pretty well. It is similar to this:https://www.staples.com/IDEAL-Circuit-Breaker-Finder-IDI61534/product_1643111?cid=PS:GooglePLAs:1643111When I worked in industry, we used a 'thumper'. It was a low RPM motor with a notched disk to trigger a limit switch which switched a 1000W heating element. We could find the circuit with an Amprobe. It worked pretty well but it was bulky.LOTO (Lock Out, Tag Out) is what keeps electricians alive. There are locking attachments for circuit breaker handles that don't require locking the entire panel. Tape over a handle is clearly not acceptable. Test the voltage tester on a known energized source, test the circuit to be worked and then test the tester again. At a minimum!https://www.uline.com/Product/Detail/H-3439/Lockout-Tagout/Circuit-Breaker-Lockout-Oversized

content: You would have to be a licenced electrician to do that in Australia. You can't legally touch fixed wiring otherwise. This, I found out, also extends to mains wiring in caravans.

content: 'Ultimate Handyman' videos get a thumbs upthey are short n sweet, straight to the point, no music, no BS and no sneaky product shillingHe's doing a great job here but his 'prove dead' routine needs better confirmation, rather than assuming his device is testing itself properlyFWIW most slackers would just swap out the entire switch assembly with a newer inferior one,rather then simply re-tap a thread and put a new screw in, that may last another 60 years...or till the premises get dropped to make way for eyesore high rise easy profit shoeboxes
