Have to run 40 amp cable for wall oven

I will be using 8 gauge.My question is can I use 8-2 copper NM/WG.It has a small ground in it. Or should I use 8-3 copper romex- not sure if it would have a ground wire in it. The run will be about 100 ft. Live in NYC.

Almost all cooking equipment require 3 conductor plus ground; which in this case would be 8-3/g. The manufacturer's instructions should specify if it is 240V only or 120/240V. If you don't know which oven it will be, go with the 3 conductor for maximum compatibility.

It is my understanding that NM is not permitted in NYC, someone else needs to confirm.

Modern cables will have a ground means.

NY is more strict than other areas. Check with your local code officials.
