1960 ELECTRICITY PRINCIPLES OF SAFETY (Circuits Fuse Voltage Amps Power Watt Shock Overload Charge)

[@gordoncrisp3060]

That police officer was pretty close to getting a lesson on voltage gradients and step potential...............

[@ironmartysharpe8293]

That's for sure because high voltage electricity will jump out at you and electrocute you , In a residential area , The power lines on top of the pole before the transformer carry 13,200 volts and that police officer was very lucky he didn't get electrocuted because that high voltage could have jumped out at him , Power lines on wooden poles can carry as high as 138,000 volts

This video is redundant. We already learned about blown circuit breakers by watching Christmas Vacation! HAHA Seriously though, great stuff!

Glorious 👍 Damn, I love this channel for bringing us gems like this

Greetings Al, glad you enjoy our channel! Thank you for the kind feedback. Much appreciated! ~ VK

That's why old toasters toasted toast faster than todays toasters. 10amps at 120vac is 1200 watts. Most new toasters (2022) draw abut 700 watts (for a 2-slice), or 58% less power than the 1200 watt toaster. Great job CHAP finding and posting this neat little film!

[@andyblackpool]

I just checked our toaster and it draws 850amps but in the UK we have 240 volts on all circuits. Our kettle is 3kw and even full boils in no time

[@brucepickess8097]

@@andyblackpool Are you sure ??????? 850 amps !!!!!!!!, how in the hell do you get that from a 13 Amp socket ??????

[@andyblackpool]

@@brucepickess8097 Ha ha yes its one hell of a HUGE toaster! Sorry, misprinted. Should have read 850 watts of course not amps. The plug itself contains a 13amp fuse 😉

[@brucepickess8097]

@@andyblackpool Hi, yes it was obviously Watts and not Amps. Just a thought, as it's 850 Watts that would draw approx 3.5 Amps. You might want to consider reducing the plug fuse rating more in line with the current demand to afford greater protection under a potential fault condition. You may get away with a 5 A fuse, if not 10 A.

[@andyblackpool]

@@brucepickess8097 The fuse was installed by the manufacturer. Fuses in plugs in the UK are to there protect the flex only; not the appliance (as weird as that may sound) But thank's anyway

Neat little film.

[@okaro6595]

1:25 Ungrounded electric devices right to a water tap. That is a death trap. In Finland sockets in the kitchen were grounded since 1930. That means you could only use grounded devices. I hope the metal cover of the socket was not grounded also.

[@MichiganPeatMoss]

...and we haven't yet discovered that a third grounding prong will be most beneficial... Barbara.

Or the "All American Five" transformerless radios with the non- polarized cords!

[@matneu27]

Nevertheless of those nice and serious movies, generations of dads where tinkering in the house wiring and "repaired" appliances ending in fires or electric shock. So it was a case of luck when the fuse had tripped 😣

[@jamesslick4790]

I'm POSITIVE that this film is still CURRENT, But WATT do I know.

That is such a NEGATIVE attitude to take! 🤣

Moral of the story: Barbara and Jimmy have parents who are too cheap to update their old wiring.

[@randyab9go188]

Knob and tube.

[@jamesslick4790]

@@randyab9go188 2022 I STILL have K&T, But it's confined to lighting circuits. Since LEDs use Wayy less power than incandescent, I'm not blowing any fuses. (House was built in 1873, originally wired in the 1910's, but the wiring to receptacles (plug outlets) was done in the late 1960's and are proper grounded circuits. (kitchen, bath and cellar is all "modern". as to the rest, Grounding would only be a hazard of I was changing a bulb in my living room while my hand was on the kitchen faucet, A scenario that is impossible, LOL.

[@jamesslick4790]

Technically speaking, No. Not the case. These were overloads and shorts. Even in a MODERN kitchen, Barbara would have tripped the breaker. Kitchen outlets TODAY are required to be 20 Amps, she put a 21-amp load on the circuit. Yeah, it blew the 15-amp fuse in 1960, BUT it would ALSO trip a brand new 20-amp breaker in 2022. Jimmy used a defective extension cord. It blew the fuse in 1960, It would trip the breaker in any modern home NOW.

[@156dave]

They must be supplying 110vac with those high currents at 220vac the current would be half that

[@mikemike7001]

But Barbara's dad can sure make a nice sketch.

[@TheFlow2006]

i always find it fascinating when looking at the american electric system that it basically stoppet evolving in the 50´s/60´s it looks now just like it looked back then

[@TheBrickCrew2013]

Things have actually changed a lot sense then. The only thing that’s the same is the basics like having a hot and neutral

[@babumanikuttan2258]

So wonderful vedeo

[@luckygen1001]

One thing this video did not get right, at 4:30 it shows the wires before the socket burning and yet the wires after the socket are not burning? Must be better quality wire!!!!!!

[@marcse7en]

Barbara saw the appliances weren't becoming heated! ... DAD EXPLAINED: "It's our crappy American electrical outlets! You can't plug two appliances into one farty outlet! It's too many amp-ears!" BARBARA: "We should go live in Britain! Their electric sockets don't cut-out when you plug two appliances into them!" 👍😂

[@andyblackpool]

Yes, and we can boil a full 3kw electric kettle in about 3 minutes flat with the toaster plugged into the same socket! 😉

[@matneu27]

@@andyblackpool thanks to the decision for the 230V grid 😁

[@matneu27]

Also all our European sockets had a third pin to ground metal cases of the frying pan or toaster and trip the fuse if a power leading wire touches the case instead setting it on mains voltage.

[@marcse7en]

@@andyblackpool Correct! 👍😂

[@thesteelrodent1796]

As someone who lives in an apartment building that's largely from the 1960s, this is too real. We have 1 phase to cover everything in the apartment except for the stove. Back then that would've been plenty, but nowaday with dishwasher, washing machine, computers and whatever else, 2300 W just isn't enough (and it was 2200 W when the building was new). We have yet to get the apartment rewired because it's stupid expensive, especially at the moment while prices are skyrocketing

In todays's days all are much safer - ladys are not cooking - just waiting for delivery. Husbands and sons do not drill anything. All sit in front of 150 W PC and monitors, lights are 10W LED impossible to overload 15 A And we still say our . energy consumption is crazy too much. .

[@ironmartysharpe8293]

I wish fuses were designed to be different diameters for the amperage For example , A small diameter for 15 amp , A little bit bigger for 20 amps and even bigger for 30 amp so a higher amp fuse cannot be put into a 15 amp socket because fuses are actually safer than circuit breakers because there's nothing mechanical with a fuse compared to a circuit breaker which the mechanism can fail Plus fuses react more quickly to overloads and short circuits than a circuit breaker and because a fuse has no mechanism like a circuit breaker does , it's more reliable and safer But unfortunately , Fuse sockets are the same diameter which many people would put a higher amperage fuse which defeats the purpose of electrical protection and that's when fires start Like I said , Fuses should have been designed with different diameters to prevent putting in a higher amperage fuse for the particular circuit

[@ComputerHistoryArchivesProject]

@ironmartysharpe8293, absolutely true! Very good suggestion. - PS I grew up in a house made in 1895, we had screw-in fuses for electrical wiring that were SAME size as standard light bulb sockets. When few blew at night and no one had a new fuse, we just put a copper penny in the socket and screwed the bad few back in again. Oh.... so dangerous!! - Thanks for your feedback!
