I am looking for a good source to purchase a replacement power cord for a ZW and KW transformers.





The ones listed on eBay do not list what gauge wire or even the length. Some have a "L" on the end which does not even look like the Lionel 'L" some are polarized and some are even three prong which I believe should not be used.





While I am at it I may consider replacing the circuit breaker as well. Does anybody have a quality source for those.

Thanks!

I haven't seen any replacement cords with plugs that match the various styles that the Lionel Corporation used over the years.

I don't think I'd want to use them if they existed.

The cords I purchase have a flange around the part you grab, which act as a finger guard to prevent someone from accidentally touching the prongs. IMHO, they are safer, and safety is trump in my book.

I buy my cords from Ted, the fellow who sells screws in the Orange Hall at York.

 

 

I like C.W.'s idea, the flange is a nice touch.  If you want a Lionel clone, I'm not sure where you get those if the eBay ones aren't what you're looking for.

 

FWIW, the actual gauge of the wire in the cord is not a huge issue unless it's very small.  1500 watt hair dryers have a 16ga power cord!  #16 or even #18 would be sufficient for the ZW, it has a maximum input power of 275 watts, probably higher briefly if you overload it before the breaker trips.

Well, apparently neither was the original cord, or we wouldn't be replacing it.

 

Truthfully, plain old lamp cord has to meet UL standards, so I'm sure it's up to the task of insulating 115VAC without issue, right?

The original cords on Lionel transformers had a heavy duty insulation.  I have a Type R that I've had for 70+ years, and the insulation has no cracks (probably should be replaced anyway).  I have several ZWs & a KW that I've had for 50 years, and the cords have no cracks.  While 2-conductor, they are not the flimsy lamp cord you can buy for rewiring lamps. 

 

Your sarcastic comment about the original cords is incorrect. The issue is not insulating 120-volts--it's being durable to withstand handling.

 

dpg:  I'm not so sure that a replacement internal breaker would be a sound solution.  It only breaks the U circuit, leaving you unprotected against shorts between any two of the 4 hot outlets, which can occur easily  Consider using external breakers on all 4 hot outputs, and feeding all ground return to through a single 10-amp breaker, tied to several of the U posts since the rivets holding the posts to the internal bus bar do lose good contact.

No offense intended RJR.  I realize the old cords have lasted a long time, I have several PW transformers that still have original cords as well.

 

However, I don't think it's necessary to spend a ton of money on the replacement.  FWIW, I bought some of the cords from The Train Tender as well, they were fine.  Who knows, they might need replacement in 20 years, but I'm guessing I won't own the transformers by then.

Breaker from WWW.ttender.com

ZW 250 square mounts to bottom

Z-22circuit bkr old style black box13.50

 

ZW 275 side mount

ZW-232Rside mount circuit breaker repro8.00

 

KW  side mount

20-22RKW circuit brkr/side mount repro8.00

 

I have installed these modern breakers and they do work well although they look different.

gunnerjohn:  Things have a habit of remaining in one's possession longer than anticipated.  The difference in cost between a cord with a heavy duty insulation and the cheap lamp wire I have in mind is minimal.  My practice when giving advice in the forum, where many forumites are not very familiar with electricity, is to give the correct fix, rather than a make-do.  The Z4000 has a lamp-style cord, but it seems to be much better quality than what I'm thinking of.  A cord such as comes on a toaster oven of similar appliance, with two distinct conductors, is what I'd use.

Dale: This AllElectronics circuit breaker P/N appears to be obsolete. I'm checking other

sources.

Just look over at Mousers,they have a number of inexpensive 10 amp breakers.

Here is one of many

The cords from Ted are:

 

SPT-2

18 gauge

105 degrees centigrade

300 volt

CSA LL39965

UL VW-1

E67474

 

Assuming I found the correct information on the web, the cords are certified with CSA.

The cords also carry UL markings.

According to CSA, the insulation is PVC.

 

I'd guess that the cords that Jeff Kane carries are either identical, or very similar.
IMHO, these guys aren't going to risk selling cords that would be inappropriate for Lionel transformers. Think of the liability they would incur.

 

I absolutely am not telling others what to use.
I am comfortable staying with the cords I've been using.

I do just the opposite. Before trashing an old lamp or clock I cut lamp cord off and use them to repair transformers or whatever. I could understand wanting to use a repro cord if it was in fact an exact duplicate but if they are NLA, any cord will do.

A lot of the work I've done has been for other people. Recycling cords won't do.

 

And down the road, when it comes time to sell those transformers, one that has been done with a neat, black cord is going to draw a much better price than one done with a recycled cord. IMHO, the difference would likely be far in excess of the cost of the cord.

 

Funny thing: My wife tends to buy a lot of lamps at the various antique shows we visit. Every lamp gets carefully cleaned (watch that patina) and rewired. Most of the time the cords are so dirty and twisted, that they are not worth saving. Here I don't use cords with molded plugs because I make up the cord length according to where my wife wants to use the lamp. I have a spool of SPT-2 wire for this purpose.

For the old lamps,they sell reproduction cloth cords if that is the look you want.

Isn't it amazing how a simple question has lead to such a long discussion?

 

Actually, there is a better solution to use of a polarized plug.  Presumably (hopefully?) all transformers have been phased and the plugs marked as to how they should go into the receptacle.  When you open the transformer case, see which connection in the transformer goes to which prong of the plug, note which hole in receptacle is wider (that would be the "neutral" &should be on the left if the round ground hole is downward), and wire the polarized cord accordingly.  You will have solved the problem of phasing transformers in the future.
