Decoding Electrical Appliance Cord Descriptors
Decoding Electrical Appliance Cord Descriptors
(OP)
Hello all,
I'm posting this one in the Hobbies forum since it's completely avocational.
The church ladies have abused the cord on one of their coffee percolators to the point its neutral conductor has developed an open, right next to the molded rubber female end of the detachable cord. Said female end has three openings in the following configuration
I
I I
and due to its molded nature I believe it to be unrepairable...perhaps someone knows of a source for replacement cord ends of this type...?
Failing that:
The defective flat-cross-section cord bears the following marking: UL E251603 HPN 105°C 18AWGX3C VW-1 RIFENG
°
I'm trying to figure out if I can replace it with a spare round-cross-section cord I have whose legend reads: E176096 [UL] SVT VW-1 105°C 300V 18AWGX3C OR C[UL] SVT FT2 105°C 18AWGX3C VW-1 UNIRISE
I'm concerned with the heat dissipating ability of the replacement round cross-sectional cord and that it may be poorer than the flat version.
Unfortunately I'm having no luck trying to find the specs behind the numbers...then again, maybe I just don't know which search terms to use to achieve the "open sesame" I'm looking for...
Any assistance would be greatly appreciated.
Thanks.

CEC 2015 Table 11 SVT Flexible cord, Damp or Dry locations, not for hard usage.
CEC 2015 Table 12 Both cords are rated for 10 Amps at AWG 18. If you actually have AWG 17, it is rated for 13 Amps. If that is the case then you may have to upgrade to AWG 16.

RE: Decoding Electrical Appliance Cord Descriptors
Artisi: a replacement cord was definitely in my mind as a possibility, but it being a long weekend here in Canada not very many specialized businesses, like appliance repair places, will be open again until Monday.

RE: Decoding Electrical Appliance Cord Descriptors
If it failed at the plug then the same old style replacement cord will fail at the plug too.
Use a replacement plug with a long strain relief to improve the situation.

crshears; This is the only replaceable IEC type plug I've seen:
[link Female IEC]http://www.parts-express.com/marinco-320iec15-iec-...[/link]
It does look pretty robust and provides strain relief.

RE: Decoding Electrical Appliance Cord Descriptors
BTW last night I needed one for a lamp cord and cut the female end off (both ends in fact) and removed the jacket and then the insulation from the three leads. I then attempted to twist the bare unsoldered strands... It was COMPLETELY IMPOSSIBLE to do! They could not be twisted. They instantly sprung untwisted to the extent of looking like I'd never even tried. I held them and twisted them about 20 turns and they'd just explode back to the original untwisted state. I was amazed.
I finally got it to work by inter-digitating the 'untwistable' strands with real wire strands and twisting the resulting system. That was really strange, I'm trying to figure out how they even made that wire. I can't believe they would include toxic beryllium in a cheap-ass cord.

It turns up from time to time in very high power electronic devices and RF stuff. We used it a lot in chip & wire hybrids for the military market, but some of the older commercial devices also used it when switch dissipations were much higher than with today's fast devices. Some older heat transfer pastes contain it too - I'm not sure if the present-day recipe includes it or not.

That looks like exactly the required part! Thanks much! I had not yet found such a beast...will see if I can find one locally @ Torbram, or Gerrie, or Guillevin International, or Ideal Supply, or...
Now that I know such are available, I can begin the [bargain!] hunt!
Thanks again.

If so, then try Value Village or other similar places. Also try the corner computer repair shop for a good used replacement.
Or, if you have a discarded laptop or other equipment. I have just checked the cords on three laptops and they all have similar ratings to your original cable. One is round, two are flat.

That being said, checking the bags on the wall at Value Village et al isn't a half-bad idea at all...thanks, Bill.

Speaking of the terminology of burning in...is there any context beyond percs where this is considered a positive thing? We've had to replace computer monitors because the permanent display gets so "burned in" that when the display changes to something else it's challenging to see the new one.
I may be wrong, but I seem to recall that "burning in" was something that was done to thermionically emissive devices, like mercury arc rectifiers, to "break them in..." or is my memory faulty?

RE: Decoding Electrical Appliance Cord Descriptors
That said,
A pattern "Burning in" to a CRT display was also a common usage of the term even though this use was somewhat at odds with the other common usage.

Funny, church coffee always seems to taste the same a all churches. Even visited a synagogue once, and it tasted the same.
RE: Decoding Electrical Appliance Cord Descriptors
Still, finding the correct replacement is a good idea because the insulation on the heater cord will withstand that use better, and by that I mean the plugging and unplugging and coiling up and such as the unit is moved around.

Answer: 1000 W @ 120VAC - sorry Bill, not only am I one week late, but also it is only now that I notice you asked for rated current, not power...

Perfect opportunity to sit down with my lad and teach him how to do a thorough inspection and use a megger (with tales of the Kray boys to keep him focussed on the H&S bits).
I was expecting low IR (the church ladies do like to dunk the bottom of these things into a bowl of soapy water while trying to fill them through the spout) - but this was a full three-core short where the cable had been repeatedly strained around the cable grip on the wall plug. Perfect opportunity to show off the arcing damage and lack of evidence of any prior long-term overheating before getting him to trim the cable, rewire the plug then test and reinspect the whole thing.
I hadn't realised how little opportunity kids get these days to learn how to wire a plug - I think it was a pretty routine thing for me from about the age of ten, yet my lad has got to nearly 18 without ever having to do it. Moulded-on connectors (or lazy parents) have a lot to answer for.
