- Welcome to show me cables. Today we’re going to be taking a look at power connectors.
The type of connections we’ll be going over are the IEC and NEMA standard connectors frequently found in data centers, offices, and home usage.
Let’s start with the IEC connectors.
IEC connectors refer to their connections as either an Outlet or an Inlet compared to the standard Male/Female or Plug/Jack.
It also uses a number system, in which the odd numbers are Outlets and the even numbers are Inlets.
For instance, the C5 connector is an outlet and the C6 is the same form factor, but is an Inlet.
C5 and C6 can commonly be found on laptop power supplies, portable projectors, and some desktop computers.
C7 and C8 can commonly be found on battery chargers, power supplies, video game consoles and some A/V equipment. These connectors are available in both a polarized and non-polarized version. The key difference being that the polarized connector will have one side squared off.
C13 and C14 can commonly be found on desktop computers, monitors, amplifiers, and printers.
C15 and C16 can be found on appliances that generate a lot of heat. It has a similar form factor to the C13/14 but with a small notch underneath the ground. They also feature a higher temperature rating, making them ideal for higher draw equipment.
C19 and C20 can be found on high power workstations and servers, power supplies, large network routers and power units.
Now let’s take a look at the NEMA connectors
1-15 are the 2 pronged power connections found in many older wall outlets that have not been grounded.
5-15 are the 3 pronged power connections found on wall outlets that have been grounded.
5-20 Are similarly formed to the 5-15 but with an additional horizontal blade and are rated for slightly higher amperage.

You know you're an adult when you're looking for that kind of information and really enjoying it
This is one of the most useful guides to the power cable standards that I could locate on the Internet. For real. You have definitely Shown Me Cables.
Thank you very much for a nice, clear, simple explanation of these power connectors. Very helpful!
Very, very helpful.. Thanks for putting this together
THANK YOU ! It's always helpful to help the right cables for power and data !
Good job, good video.
I subscribed and i LOVED this video.
I was confused about which cord i should buy because my old c7 non-polarized cord wasn't working properly but this video helped me to decide
Wow. Excellent video. This is so helpful. Thank you.
Would be even more useful to give design specs for amps and voltage for each connector.
@@stevejohnson1321 That can't be as they are also used in the EU. Without downloading IEC 60320 i'd guess at least up to C16 the insulation level is 1000 V as they are used for 240/400 V systems. Allowed amps are on the wikipedia page. That info could be added with an overlay without reuploading the video.
@@thoreberlin Apologies. I've removed my follow-up.
I’m just amazed that ShowMeCables has a UA-cam channel!
Very useful video, Thanks!
Pretty useful...thanks very much!
You should have mentioned that a C15 cable fits in a C14 device, but C13 cable doesn't fit in a C16 device. This allows cables rated for high temperatures to be used with many devices, but high-temperature devices won't accept cables not rated for it.
2:17 It doesn't have an "ADDITIONAL horizontal blade", it has a horizontal blade INSTEAD of a vertical on that side. The 5-20R socket allows use of either the 5-20P plug shown, OR the 5-15P plug at 2:08
ok captain obvious
It isn't instead though...
It would have been helpful for them to mention the actual AMP ratings of the more common 3 prong, and AMPs on the 5-20P
It's obvious he meant the socket has an additional slit for that blade. They were both on screen at the same time. Your life must be difficult if you can't comprehend this based on the context. I bet you go around irl correcting people's spoken grammar.
Cool, thanks for sharing
Very helpful!!
Super helpful! Thanks!
This is a great video!
Thank you. Very helpful
Good guide ❤ Thanks
C13/14 in Australia just named kettle plug as in old porcelain kettles used them. Standard tv and desktop plug, guitar amps etc. C7/8 some tv's, portable stereos, shavers- called shaver plugs in Aust. C5/6 a few laptop chargers, a lot of LG tv's. Always have numerous of all of above cables on hand as i try to repair telly's etc from e-waste with about 30% success!
The shaver plug is different, slightly smaller and the plug has straight side edges.
well the plug vs jack kinda gets a bit inverted on the power cables so it makes more sense to use outlet and inlet (since it's also pretty obvious which side is which by checking which has exposed Pins
Very very very helpful
awesome!
I wish you had let in the NEMA 6 series. And perhaps connectors for bigger than 20A.
i so luv the plug cause its current
good job
Hi, im trying to find a specific connector for a launch sega saturn, its similar to the universal power cables however it is not slotted, it is however polarized. Example, if the non polarized example of what im looking for looks like a 0 instead of an 8 then the one im looking for would be shaped like a horizontally stretched D. Any advice?
I many power adapters and I understand the power cord connections into the "block" or converter. What I am having issues with are the varied connectors into the devices. You have connectors for Dell laptops, Toshiba and so on. There are even a couple I have that the device connector is approximately 5/8" OD, with three pin inside. Similar to the connector for a Ford Mustang. So can you help with understanding what all these device connectors go to? Thank you.
did you just use blitz video ending song?
nice video，bro
I have an old VCR that use the C7 connector and I have a power cord that looks the same, except it doesn't have the notch in the top and bottom. It does have the squared off end. Can I just cut a notch in the cord end to make it fit?
Very helpful video .n
it is very helpful.. you should also include C23/C24 in video..
Wait so it was an educational advertisement 🤔😆
I now know that a Mickey Mouse/Cloverleaf connector is an IEC-C6. Thanks.
What other electronics use a c7 cord?
1:27 On C13 Which one needs to be the phase? Left or right side? On this frame.
2:23 Wait, this was an advertisement the whole time!
Which side of the squared off C7 and C8 connectors is hot?
1:27 C15 and C16 power connectors for home appliances generating high temperature, of higher heat rating 120c.
C15 female, C16 male both with a small notch at the ground.
@ShowMeCables or anyone, can someone tell me IEC C7 non polar plug is designed to work inside a polar IEC C8 port? Vizio has this exact setup with their new OLED TV's and it is concerning me because it seems like a terrible, mismatched connection.
They all have different faces but do the same thing right? I.e they all just deliver the AC power from the wall socket?
I have a table fan with a long cable and am researching the possibility of cutting it amid and reconnecting the two ends with C7 and C8 instead so that the C7/C8 can go thru small holes on a cabinet door. Is it doable? Or is there other better options? I’m surprised no one really talk about it on the internet 🤔
im buildinga 400 watt custom case... i cant decide if i go with c6 or c13??
I would say go with c13
NEMA are not appliance connectors. Those are wall connectors. So should be compared to CEE 7 standards, not to IEC 60320.
NEMA 5-20P (Appliance) + NEMA 5-20R (Wall) = Appliances (High Amperage Appliances - We have a big Air Conditioner that use these.)
Why do C13/C14 in computers and power bricks often come loose so easily? They wiggle like if the receptacle doesn't have completely straight sides. I need to shove the plug in with force and hope it sticks and I won't need to touch it to dust it off.
I'm not really a fan of NEMA sockets... Plug something halfway in with exposed contacts and still the thing plugged in still work.
This is pretty much every US plug in existence.
No shielding on contacts near plug
@jockadoobee Tell me about it.
In Australia we have AS/NZS 3112:2000 which says that the Live and Neutral Pins must be insulated at the plug end and half way down the shank.
What about the difference between the 5-20 and 6-20? What's that all about?
No Hubell T blades? (banned since the 50s) my house had those in every outlet. Id like to know what devices actually existed that used it.
You mean the outset that had T-shaped on both and no ground? The original design by Hubbell had the blades horizontally, after a few years he changed them vertically. because bit were used sockets supported both.
thank god
If my house has mostly Nema 1-15R Can I or How would I be able to use my power outlet strip if it has 3 pogs???
You can get adapters that take have a 5-15R on one side and a 1-15P along with a ground lead on the other. You plug in the 1-15P to your 1-15R and then screw the ground lead into the box, usually through the screw in the center of the faceplate. Make sure to use an unpainted screw, and double check the box is grounded. If the box isn't grounded, hoo boy. You should probably rewire.
If you cannot rewire the outlet you can replace it with a GFCI outlet, perfectly legal.
I've lost my treadmill power cable. It looks like a C13, but it's bigger than the desktop computer c13. Any idea what I should be looking for?
The instruction manual.
@@gladiammgtow4092 🤣
Can I connect the polarized c7 plug with non polarized c7 jack?? please help me
Assuming you mean a polarized C8 plug with a non-pol C7 jack: Yes, you can.
However, a non-polarized C8 plug won't work with a polarized C7 jack.
@@Grizzly01 never try it. I have done this few months ago. My hair clipper capacitor already instantly explode when switch on.. But nevermind, such new experience for me.
*DC plug has left chat*
Why are your NEMA connectors upside down?
I won't speak for them, but I've found it's better to have the ground pin facing upward. Why? Because if the plug is only in half way and something falls into the gap, it is better that the offending item touches the ground and doesn't short the live to the neutral. That's bad news.
Male and FEMALE were put in the wrong order at 0:30.
JACK and PLUG were put in the wrong order at 0:33.
BLITZ OUTRO MUSIC
That is my fetiche.
Never heard of "NEMA" is this a US only thing?
I assume so, since all of the plugs that were under NEMA were ones I'm aware were found in the US mainly
yeah , it's the outlet we have on the walls in the US
Why do polarized c7 cables exist. Really weird
I have a psu that uses c19 😐
what about powercon
Powercon is a patent owned by neutrik and not a standardised power plug like the IEC line . Hahaha
Wouldn't the one's below be Female and Jacks?
No, the 'maleness' refers to the conductor pins, and the 'femaleness' to the sockets that those pins go into.
@@Grizzly01 yeah lol, right
@@Grizzly01 I had a prudish teacher in the sixties who tried to explain reproduction by plugging an extension cord into a wall receptacle. That metaphorical demonstration sparked my imagination, because I didn't realized until college that there weren't three anatomical "sockets."
@@jtrice6852 🤣🤣
Well, technically there are, but you certainly can't plug something into all three at once without help...

0:54 umm... *ALL* MacBook's use the "Figure 8" style IEC Connector for power and not the C5 Connector, and PC's (including Mac's, and Mac Pro's), uses the "Kettle Plug" Style Connectors!
*EDIT:* Youll see the C13 and C14 on *ALL* PC towers and Mac's
Macbook =/= laptop, and not all PSUs use C13/C14
@@olican101 oh yeah my mistake, I should have known, (I'm an idiot). They also use the cloverleaf style connector as well oops!
BTW Thanks dude!
@@olican101 Of course a MacBook is a laptop.
So many 'standards'. Perhaps there is no standard?
Maybe we can just use ONE TYPE. That way you don’t have dozens of cords around and STILL don’t have the right cable 😬.
Ok. I volunteer you to charge your laptop or phone with a 208V 3-phase 50A feed line.
dm me ur cables (;
Why so many? Why can't there be a world standard for plugs and connectors? Oh, wait. That would require humans acquiring intelligence!
It's actually because of intelligence they invented these plugs. These standards are made from their previous iterations. There will be newer and newer standards after they found some problems or specific needs to be addressed.
@@dputra You are confusing intelligence with cleverness. Humans are clever and invent many things, some good, some atrocious. Other animals are far more intelligent since they do not breed way out of the numbers their environment can support; they do not routinely pollute their living space, and they do not destroy the biodiversity of the planet - only humans do that.
stupid multiple standard connector
