The dishwasher is permanetly attached however the cord for the washing machine I was talking about is an extension cord. I have seen them listed specifically for washing machines. I should have made that clear.celtic said:

Not if you had to pay a UL Inspector to come out an re-certify the equipment?
(Or do they do such things? :-? )
Charlie b
Why would he have to come out? We change cords on vacs, other items at home and we don't think twice about those things. I thought it was an very good idea to add some length to the garage door opener.

I believe my supplier has some-- I'll get the info
AND of course I didn't think you'd let me get away without proof.

Dennis how does that cord get us around the rules in 400?

I will be honest Bob-- I am fishing for the sake of understanding art. 240.5(B)(1) and (3).
Art. 400.7(A)(10) allows cords where specifically permitted elsewhere. If this is a listed appliance cord would it not be okay for a garage door opener. I don't see how 400.8 (1) is really affected by this. See my post #17
What other part of 400 are you specifically talking about.

And the reason is.....
Do you really find replaceing a cord on any cord connected item to be a problem.
This is an example of throwing out the code and replacing it with common sense.

You should not make this as a blanket statement.
1.) The UL listing is a verifcation of how it left the factory, you can not change that.
2.) UL says that any field modifications (including punching conduit entrances) need to be inspected before even they would be able to claim them as adversely affecting the product.
3.) Replacing a cord (including the cord grip) or a cord end, is the not same situation as adding a cord to a product that was intended for conduit connection (and vice versa).
4.) The length of the cord supplied with a product may not even be a factor in the UL Listing process. Yes counter top appliances are limited in length so they won't hang off of the counter, but in most other cases the length is chosen by the manufacturer instead.
Why not?
I didn't say "You must not..."...or "it's a violation of article xxx.xx"
I said exactly what a professional MUST consider when altering the UL listing : If you are comfortable negating the UL listing ...
That "blanket statement" puts the onus of having the relisting on the professional.
Going back to my other post:
Doesn't it occur to you that the lenght of the cord is specific for a reason?
GDOs typically come with a 3' cord.
Why is that?
How did it become so "typical" ?
Did all the manufac.s collective agree that 3' should be the length?
Think it may have something to do with the unit's listing?

Sure are a lot of responses about changing the power cord and UL approval.
I?ll make it worse then. :grin:
I see so much unsafe garbage with UL listings anymore that I consider a UL listing to be a mere joke in many cases.
Does anybody really beleive that changing a power cord on an appliance will make it unsafe?
Why is the power cord treated any differently than an extention cord by the NEC?
And the only purpose of my first post was to be amusing, not to condone breaching compliance.

A 3 ft. cord is cheaper than a 6 ft. cord and it's normally long enough.

I find this is very interesting for something so simple.
First I doubt if the same people that manufacture the opener even manufacture the cord ( it has a seperate UL listing ).
The reason the the cord is four feet is because this works out well in most cases without have a lot of excess cord hanging around.
You probably could run a longer cord ( UL listed ). But why would you want to ?
It appears that the manufacturers will allow you to hardwire the motor if you need to. ( they give instructions for an electrician to do so ).
So you could move the receptacle or hard wire with switch for disconnect.
If anyone were to use a longer cord it would be a good idea to contact the manufacturer and get written permission to alter the equipment.
If I find one that is to far from the receptacle I think I''ll hard wire with MC cable. It will look better and I can charge more. ( yes, I'll swap out that little plastic box for a metal one and probably use an industrial rated switch as disconnect it bumps up material cost ).

All the GDO headhonchoes met at a Motel 6 and said " Let's go with four feet because this works out well in most cases "
Actually I'm not kidding. 4 ft. is not an industry standard. Some manufacturers offer a 6 ft. cord.
In product development it's hard to engineer for every possibility so it comes down to what works best most of the time. If there was a demand there would probably be a cord retractor like a vacuum cleaner.
Yes, NEMA does hold their conventions at Motel 6, they have been kicked out of all the decent hotels.:roll:
