Electricians: Range wiring and breaker sizing code

[buickanddeere]

If something at the end of the lamp cord drew 19 amps, the cord would get very hot, and melt its insulation, and then the cords wires would likely touch, and draw a lot of current for a very short period of time and the breaker will open. I think what you are getting at of course is that nearby flammable materiel's could be ignited.

Seems to be everybody is forgetting the breaker supplies short circuit protection first and foremost. The device plugged in is supposed to provide it's own thermal protection . Is an explanation needed for short circuit protection and thermal protection which are different.

#6 wire is good for 60 amps. If you install a 40 or 50 amp breaker you will satisfy the range over current protection as per the range requirements, your wire will actually be one size to large which will not hurt a thing. Install the breaker and the inspector will be satisfied. Very simple fix. Someone may have already told you this but I did not take the time to read them all, good luck.

Better not be plugging a stove or dryer into that plug. In fact that plug is long obsolete. The only thing now that would be close is a 277V or 347V single phase receptacle .

That's a very common 220v receptacle here... even find it in the hospital operating rooms for the lasers.

Literally thousands of homes have them here in the East Bay of San Francisco.

My welder is plugged into the same.

It's three prong so it should be used on an electric dryer or an electric stove as there is no neutral .

And...?

 

[buickanddeere]

#6 copper wire depending on the insulation is rated for between 55,65,80,85 and 95 amps.

Why would one want neutral on a 240V range?

Why would one want neutral on a 240V range?

Because the timers, electronic controls and oven lights are 120V. That's why they changed to code to require 4-wire on new cable installations.

Depends on the stove... Most of the controls are low voltage these days, so one could use a 220v-24v transformer without much fuss if there was another solution for the light (24v LED anyone?)

Good answer

Wow, this has gone 9 pages. Has anybody mentioned that he could upgrade the receptacle box and range cord to 60 amps instead of changing the breaker?

 

[JimRB]

I think earlier he mentioned the stove or range was marked as a 40 amp device. It takes a lot less time for me to change a QO breaker than it would take me to replace receptacle, receptacle plate and range cord. And I would spend a lot more money than a $16 breaker.

 

[buickanddeere]

Why would one want neutral on a 240V range?

To carry the neutral current from the electronic controls and the 120V receptacles.
Are you going to start talking again about something you don't understand and tell us a falicy that ground and neutral are the same ?

Said it again as some of you were not getting it through your heads.
