Hi,

How much current can copper strip handle, DC current, provided the length L, width W, and thickness t?

You need to define “handle“.

Are you referring to a desired max temp rise?
The melting point?
A certain voltage drop?
In open air or under fishpaper/heat shrink?
If in open air…fan cooled?
With heavy wiring or lugs close by or longer strips of just copper?

Circuit board trace width calculators are good for this. I'd keep the internal layer temperature rise under 20°C for the hottest days.
