Supply Wire for Double Oven

We have received a hand-me-down GE electric double oven that we would like to install in our kitchen - which we are currently remodeling. So far, I have not been able to find a definitive model number to guide me on the oven's exact electrical requirements - but I confess I've only checked the areas that are convenient to get to and haven't gone looking on the bottom.

The ovens have a single metal conduit with 4 wires coming out which I will eventually connect to a junction box within the cabinet that will house the ovens. My question is what KIND of supply line should I run to that box? When I say that - I do not mean what gauge (since I will eventually have to determine the model to determine the breaker amperage and wire gauge) - but will this be a single fat cable or 4 separate wires in a conduit? If it is a fat cable, should I try to run it through the joists in the basment, or below them? The reason I ask is that I am running other electrical cables in the basement right now and I am trying to plan ahead for when it is time to connect the oven.

If NM type cable is allowed where you live (and it is in most places) then you can run NM (something like 6-3, which will have three insulated conductors plus a ground). You can also run conduit and then run individual conductors, but this is more work.

Most likely, the cooking appliance requires a 40-amp Branch-Circuit. This is effected with #8 copper conductors. It's best if you can verfy this;what you need to know is the "wattage-rating"-- ex: 8KW---- search for a name-plate for this specific info.

As to the Wiring Method, if you use non-metallic cable, type NM, and are installing N-M cables for other circuits, the important Code-consideration is "protection from mechanical injury" . If you want to secure the cables to the bottom of the joists, I suggest you route the cables between two 2X4's fastened to the joists and set parallel to the cables. When all cables are in place, cover the cables with S-R fastened to the 2X4's.

Good Luck, & Learn & Enjoy from the Experience!!!!!!!!!!!!
