220 Volt Wiring Guidance for Kitchen Remodel?

Sammy Kar: 1. You can do a splice, do it in a box using proper technique for your electrical code, likely wire nuts are acceptable everywhere.2. I think you need a new circuit for the new oven. I think you need four wire, that is, 3 wire with ground. That way both hots, the neutral and the ground are at the appliance. Your appliance information will tell you.3. Use only copper and appropriate for the breaker that will power the device. Codes vary, I think 8 gage wire can do 50 amps if it is THNN insulation, but check to make sure starting with your appliance handbook, electrical supplier, electrical inspector etc.happy cooking...Show more

Donita Desjardin: Not enough information to give you a correct answer. The others are guessing. Will this work be inspected? Do you want it to comply with the electric code? Including any state and local codes?Just for your information, it is 240 volts in the USA.

Vita Moodie: This work will not be inspected, but I would! like for it to be done properly. The cook-top needs 30 AMPS and the double oven requires 50 AMPS. We are currently planning on running the existing wire that goes from the breaker box to the range/oven to the new double oven and we will be installing a box so that we can splice a line to the oven for the remainder of the distance needed. We are running a new 10/3 wire from the breaker box all the way to the new cook-top for the 30 AMP service.I hope this provides some much needed information in order to give a complete answer!Thank you!...Show more

Ulrike Hert: you can tie into the existing line useing a junciton box, to make the splice, use tha same size wire to extend it,

Lyndon Mattas: One more thing I may need to figure out. How do I find out if my home has 240V or 208V?

Ronnie Sardi: You can put the wires in a junction box and add enough cable to run to your stove top....use the same size wire if for nothing else other than safety.....you need t! o run a new wire to your double oven from the breaker box....y! ou cannot tie both the double oven and the the stovetop to the exisiting wiring because if you were using all the burners and both ovens the old wire and breaker would be overloaded...you can get by with 10/3 with ground and a thirty amp breaker to the stove top but i would use 8/3 with ground myself...and you need 6/3 with ground to the double oven with a 50 amp breaker.....you could have from 230 to 250 volts but not 208 as that usually is only on 3 phase systems... when you make the splices use a device called a split bolt connector as it will make a better electrical splice than a wire nut....nearly all states codes will allow the wire to the stove top to be spliced and anyone who is the homeowner can do the work hisself .....you might have to get a permit in your locality to do the work though....some places might require an inspection but some localities do not require an inspection.....you need to watch prople who verbally abuse others as they use this to make you t! hink what they are saying is the right answer....I have been a master electrician..master hvac tech, certified oil and gas burner tech...appliance tech and pump specialist for 40 years ....our family has been in this business for a combined 95 years........Show more

Ramon Dahlheimer: You can use a junction box and make your splice inside that. The box needs to be in a accessible location. Like in an attic or crawl space. I could be mounted flush with the wall and have a cover plate on it to. It just can't be hidden in a wall or behind a permanent cabinet. The wire has to be the same size. Look on the existing wire and it should have a size. If not take some of it with you when you buy the new wire. Use the proper clamps coming into the box and staple the wire with in 6" of the box and use large wire nuts, like grey, to connect the wires....Show more

Randal Deyarmond: Your best bet would be to hire an electrician.Here you have one ,who claims to be,real electrici! an who read you question and is unable to understand it.I have seen oth! er questions he don't understand,too Senile Dementia maybe. There is another who claims to be a master electrician who must work for the fire department,because his answer is way out there wrong.Sure they are!Ovens wire size # 6/3 w/ground,that's four wires new code,50 amp 2-pole breaker.I personally don't like to splice into existing circuits for new equipment,and my knowledge of codes stops me.Cook-Top rated 30 amp.# 10/3 w/ground 30 amp breaker.Residential 120/240.208 volts is from a 3-phase systemFrom seeing the answers here,please be careful taking advice of DYI's.Sure it was working great before the FIRE !...Show more
