Sub-Panel in Garage

I am currently finishing my basement and before I close in the walls and ceiling, I am think of pulling the wire necessary to add a 40amp sub-panel in my garage for my table saw (when I upgrade to one requiring 240). My understanding is that 8/3 cable should be enough for that.

My question is that since my garage is attached to my house, can I pull the the white 8/3 that is used for inside or should I pull the black wire that is also rated for outside/underground?

Yes, use the white one.

Use the white one, but I would run a 6/3. Then you can put a panel in the garage at a later date. Otherwise if you want any other receptacles/lights you will need to run a new cable from your basement. This will give you 60A which is plenty for a garage. EV chargers can add more to that but there are ways around it with a load miser.

Thank you both for your very useful comments.

Anyone know where I can get 6/3 (white) cable? All the big boxes are out around me (Hamilton).

Can I use the black external cable if I can't find the white wire?

Hi once more.

Having a hard time find the internal 6/3 (white) but can find the black stuff here. Will this be sufficient if I can't find the white?

You really should be hiring an electrician at this point. Do it "once and do it right" + you will get a warranty. If your house burns down, a amateur doing it, this voids your insurance.

John from Edmonton.

Not a helpful comment. Pulling a wire does not require an electrician. Furthermore I have the appropriate permits and inspections from ESA so my insurance is not void.
