hi,
i'm wondering what the code calls out for upgrades to
kitchen service wiring.

Here's what I've got:

Installing a new cooktop appliance that needs to have 3wire/1phase supplied to it, but I've currently got
2wire/1phase wiring that's in this 1977 house.
I plan to call an electrician for this rigging, but
have a Question Relating to the
implications so as to try to anticipate the cost:

The current 2wire/1ph that supplies the old cooktop also
supplies the oven(found out by switching off breaker and
seeing what else no longer operates).

Q1- if the Electrician runs a new line to my cooktop
location but sees that the old wiring also runs to
the oven, does this imply that he would also have to
upgrade the connection to the oven?

Q2- since there would be a new line that replaces what was
previously hidden in the walls, does that imply that I'm
gonna have to have some of that unsightly conduit routed
around visibly in the kitchen??

Can anyone comment? All thoughts would be appreciated.

tia, kennetht.

MOST LIKELY YOUR NEW COOK TOP IS USING BOTH 240 VOLT AND 120 VOLT THUS REQUIRING AN INSULATED NEUTRAL NEEDING A BLACK,RED,WHITE, AND BARE. YOUR OLDER WIRING PROBABLY HAS A BLACK,WHITE,AND A BARE. DUE TO THE FACT THAT THIS WIRE FEEDING YOUR OLD RANGE IS EXISTING THEN THE NEC ALLOWS YOU TO CONNECT THE NEW COOK TOP IN THE SAME MANNER. YOU REALLY SHOULD CONFIRM THIS WITH YOUR ELECTRICAL INSPECTOR AND YOUR ELECTRICIAN, MAY BE DIFFERENT IN YOU AREA. IF YOU DO USE THE EXISTING TWO WIRE BRANCH CIRCUIT HAVE YOU ELECTRICIAN CHECK IT TO SEE THAT IT CAN CARRY BOTH OVEN AND NEW COOK TOP.

THE ELECTRICIAN DOES NOT HAVE TO REPLACE BOTH, BUT HE MAY ADVISE YOU TO REPLACE BOTH, SAFER THAT WAY. IF A NEUTRAL IS USED.

MOST OFTEN THE WIRING CAN BE FISHED INSIDE THE WALLS FROM THE PANEL TO THE EQUIPMENT AND WOULDN'T BE VISABLE.


Good luck
