4 Prong plug for stove?????

[bczygan]

If you have an existing 3 wire, what kind and size of wire would you run to get the 4th (Ground) wire?

 

[wyliesdiesels]

I realize that in some cases it may be difficult (or costly) to run a new wire, but if the local electrical code requires a 4 wire receptacle, then I would think prudence dictates that you do it.

4-wire recepticles ARE required everywhere...for new construction. Existing 3-wire receptacles are grandfathered in and are ok...

If you have an existing 3 wire, what kind and size of wire would you run to get the 4th (Ground) wire?

If the existing circuit is done with a jacketed cable such as NM/NM-b then u cannot ADD a grounding conductor. A new cable must be run...

read it again! that applies to the cooktop, not oven!

More semantics... The entire unit is made out of non-conductive materials?
That's what determines the electrical connection, not the surface of the "cook top".

Zero difference. Stove. Oven. Range. Semantics... The electrical requirements are what matters. I could see if it were a 120VAC cook top things would be different.

Tommy

No exposed metal? Your oven is made out of plastic?

Tommy

You would fail badly working in an appliance store. It is not semantics, it is like saying you fill up cars and big rigs with gas.

There is NO metal exposed during normal use. Only on the underside that one may touch when servicing the unit. nothing a person would touch in the course of cooking a meal is metal.
And no 120v used at all.
And the installation meets current code as the circuit was installed in 1967.

The oven was upgraded to a 4 wire when changed.

The application of common sense is more important than 'semantics'.

This is a place to test ones understanding, this and outlet ratings where code specific applications are listed for cooktops, ranges, even circuits involved in vented cooktops etc. What would be allowed to be combined on a circuit etc.
There is a huge amount of wiring principle involved in those code sections.

In your sense of my definitions, yes, I would fail describing the items to the customers. What I was driving at was as far as the electrical application goes, what the unit is called has next to nothing to do with how it is wired. Oven, stove and range are different items, I cannot disagree with you on that.

What really can be confusing is inthe traditional definition, a stove is not a dedicated cooking appliance. It's just a heat source. An oven or range has a stove, but a stove is not an oven.

I got ya now. I screwed up. I was looking at the "I replaced my oven" part and got my head stuck on that and completely lost sight of the fact that the cooktop might not be part of the oven.

Sorry for being such a *******...

An oven and a cooktop are part of a stove. But an oven is just the cavity, single or more. A cooktop is the burners and with the new ceramic, there is no metal to touch.
A stove is the basic all in one. Then we can get into the drop in's and such.
Maybe now you understand why a microwave is an oven and not a stove.

Cant i just run a seperate ground wire from stove frame to a good ground rod drove into the ground outside? Wouldnt that be the same?

 

[Stuart in MN]

To be clear, the NEC uses the terms
- range
- cooking unit, counter mounted
- ovens, wall mounted.

No!
A ground rod serves a totally different purpose than the equipment ground run with circuits. The earth has nothing to do with clearing faults and tripping breakers, this is the job of the equipment ground.

The equipment ground gets its functionality from the neutral to ground bond (main/system bonding jumper) in the main panel.

 

[Mustang51js]

Just hook up a 3 wire plug and cord and be done with it,or run a new line

 

[sberry]

I believe they are rather fussy about semantics in parts of the code including very specific language with regards to cooking but,,,,,,,,,,,,, it has been years since I read it.

Went thru this while installing a welder outlet in my garage. I installed a 4 prong, then changed the welder over to 4 prong. At least the house is to code and the welder doesn't know the difference.

Can you explain? Why would a welder need a 4-prong? Or did you install it for something else?
