I have 30A 240V in my garage/shop and it handles al my lighting and power tool needs. |

What we did in the past is to provide provisions for a future 100A service like underground conduit and sub panel sized for 100A but pull 30A cables for now. If the OP needs 100A for the shed, he has to upgrade the house main panel anyway. I have lots of power tools like drill presses, table saws, planer, compressors, welder etc. but I only use one tool at a time so 30A at 240V is more than enough until I install an AC unit. |

We ran a detached garage 250' from the house for 40 years on a buried 10/3.
