Can you downsize the whip on the hot tub?

stanfortyman · Feb 2, 2013, 03:14 PM

"The" hot tub? Which hot tub is that?

How about you start by telling us something about this project? Then maybe someone can help you.

220V 60 amp line (#6) to the 60 amp GFI disconnect. Can the whip to the tub be downsized at all? I know the ground is but what about the 8' whip?

No you may not downsize. 60 amps needs 6 awg Electrical Wire Sizes - What Size Electrical Wire Do I Need Try to answer Stanforty's questions.

stanfortyman · Feb 2, 2013, 09:04 PM

Correct. If the disconnect had a 60A breaker then #6cu is the smallest wire you can use.
The tub may not require a 60A circuit though.

Tell us more about the tub and we can tell you if you have any other options.

Just wondering because I seea lot of 220v 50a double ovens with an attached whip and it will be #10 wire.

Whip on an appliance that is installed by the manufacturer is different than a whip that must be installed in the field. The whip on the appliance was present, tested and listed by UL as is.

The "whip" on a hot tub is installed in the field and is nothing more than a continuation of the branch circuit, and must be sized the same as the branch circuit.

Last call, please answer Stan's questions.

I understand UL listed, but you did not answer the question in theroy. What do you mean by " answer Stans questions?" He needs more info? FOR REAL?

Thanks ballenberg. The jobs already done, I used #6. Don't know the draw, just specified 60 amps. I just though it was an easy question that could be easily explained... seems like if a double oven down sizes the whip because its tested and ul listed then they woiuld list it as the size of the whip. The whip is also just a continueation of the line. Stans not making since with his analogy.
Thanks anyway guys

Neither are you! Comparing an oven to a hot tub? How in the world are they similar? Because both are 120/240V loads? Sorry, that doesn't cut it.
It's only in your last post that you even told us the specs on the tub (that it calls for a 60A circuit). That is what I was asking. You just kept comparing it to an oven with giving us any details about this tub.

Sorry if our mind reading skills were a bit off today. I'll try and do better next time.

dcrigger · Feb 3, 2013, 03:39 PM

Sorry Stan. I did say 60 amps in a couple of post ago. OK, lets change gears. How about an oven. I am asking why an oven is rated at 50 amps and has a #10 whip?

stanfortyman · Feb 3, 2013, 05:13 PM

I am asking why an oven is rated at 50 amps and has a #10 whip?

Because an oven whip is not under the jurisdiction of the NEC. It is overseen by UL. As long UL testing considers it safe and adequate it gets a listing.

dcrigger · Feb 3, 2013, 06:33 PM

Thanks Stan, now I get it. Never thought about it that way. I those cases the oven must never pull more than 30 amps for a long period huh? Same theroy as a 20 amp appliance circuit and using a 15 amp duplex, it's rated at 15amps but by code it's OK.
Go figure...
