Hello and welcome to Just Answer. My name is ***** ***** I will be happy to assist you with your electrical question.

1) Will the cooktop be hard wired or cord and plug connected?

hi Kevin

i was connected with John before
Customer: replied 4 months ago.
im not sure whats the difference between hard wired and plug connected
Expert:  Kevin replied 4 months ago.

Cord & plug connected is using a wall receptacle.

Hard-wired is using a flexible conduit whip directly to a junction box.

Thanks for the pic.

1) Give me the model number of the AEG cooktop. I need to review the spec sheet.

Customer: replied 4 months ago.
wires from cooktop are inside metal hose. I connected red to red, black to black and green to white. And the bare cable from outlet is not connected now. Cooktop is working. but im still worried i did something wrong. I doubt there its grounded now.

ok 1 moment please
Customer: replied 4 months ago.
says on the bottom AEG 6410k-m
Customer: replied 4 months ago.
i could take a picture of wiring if you need
Expert:  Kevin replied 4 months ago.

1) The metal hose is called a flexible metal conduit.

2) The cooktop does not contain a white neutral wire. Therefore, the house white neutral wire will not be used, so cap it off with a plastic wire nut.

3) Black to black and red to red is correct. Splice the green insulated ground to the bare copper ground.

4) You originally mentioned the cooktop contains 1 black, 1 red and 1 green. Is this correct?

5) Is the white wire a house wire or a cooktop wire?

6) If you are transitioning from a flexible whip to a cord, the splices need to reside in an accessible junction box.

can you see picture i just uploaded?

Cooktop contains 1 black 1 red and 1 green

white wire is house wire
Expert:  Kevin replied 4 months ago.

1) The white wire will not be used on the cord. Install a junction box and cap off the white neutral cord wire with a wire nut.

2) Splice the cooktop green ground wire to the cord bare copper wire.

install a junction box? i dont have any
Customer: replied 4 months ago.
white one wont be used at all?
Expert:  Kevin replied 4 months ago.

Make a Home Depot run and purchase a metal box.

Ideally, the whip should connect directly to a house wall box and not to a wall receptacle.

White is not used. the cooktop doesn't contain a white neutral wire.

If using a wall receptacle, the receptacle should be replaced with the proper type. You are better off to hard-wire the cooktop

Customer: replied 4 months ago.
will junction box be that necessary? can i simply connect wires together and isolate them well afterwards?
Expert:  Kevin replied 4 months ago.

All wire splices must reside in an accessible junction box with a cover. It is a code violation to have open air splices and this can result in a fire.

The installation instructions I located are very poorly written. I need to know the amperage of the cooktop or the wattage rating. We need to confirm if the existing breaker and wiring is correct.

im attaching another picture.
Customer: replied 4 months ago.
ok i will go get junction box at nearby hardware store.
Customer: replied 4 months ago.
i have 25min before it gets closed
Customer: replied 4 months ago.
there is no need to ground it? Did I understood correctly?
Customer: replied 4 months ago.
junction box will serve a safety code purpose only?
Expert:  Kevin replied 4 months ago.

OK, the nameplate rating pic helps.

The cooktop is rated at 240 volts and 6400 watts. The circuit breaker needs to be sized as a 30 amp double pole breaker. The house wires need to be 10 AWG copper.

6400 watts/ 240 volts = 26.6 amps. Round up to next trade size breaker using 30 amps.

The cord and wall receptacle need to be replaced using a NEMA rated 6-30R and a 6-30P. The cooktop does not contain a neutral, therefore your original NEMA 14-30R receptacle and cord needs to be replaced.

Hard-wiring the cooktop may be easier.

The green and bare copper are the equipment grounding wires.

Expert:  Kevin replied 4 months ago.

You need to replace the existing wall receptacle and cord. Using the existing 4 prong cord is providing a false sense that a neutral wire exists on the cooktop, yet there is no neutral wire. You need the correct receptacle and cord plug.

A NEMA rated 6-30R and 6-30P will be a 3 prong receptacle and a 3 prong cord. Your cooktop only contains 3 wires (2 hots and 1 ground), thus the reason you can't use a 4 prong cord.

ok i see. I will save this page for reference and will run to Rona right now to ask replacement
