Reply to comment by tacodorifto in Running wire to power this 20x10 shed for an office. What wire do I need? by skinnywolfe

It would need to be about 80-100 feet of wire to account for bends through the conduit and into the attic to tie into the main panel.

There would never be more than 1000 watts of power used at any given time. More like 600W

You also need to look at total amps. I think amps is more important.

But someone who knows more can chime in.

I probably should have posted this in an electrician sub on second thought

A heater uses up to 1500 watts by itself. Extra power is handy for outside electrical tools and electric snowblowers etc

Make sure to follow the local code for your area, especially with burying the correct cable and protecting if (surrounded in gravel, pressure treated board on top, orange flagging tape…..).

A friend put a shovel through the 240v unprotected wires going to garage, while digging window well. Fortunately the breaker tripped

Run 8/3 Romex in conduit. On you main feeding your sub put a 40 amp breaker. Your sub can be a 100 amp no problem cause your feeding it with a 40 so it’s technically a 40. If you wanted to do it cheap buy 12/3 run it on a split 20 and that will do what you need at 1/4 the cost. No sub panel needed just run direct to plugs and lights but get 20 amp plugs and switches
