This is clearly a matter for debate among fire inspectors, as I have been told in other circumstances that daisy-chaining power strips is OK as long as each power strip has it’s own built-in over-current protection device.
If we aren’t allowed to daisy-chain power strips, then we will have to redo a lot of the set-up on the east wall, which has a lot of power strips daisy-chained, and which he didn’t complain about. We would need to have a lot more wall outlets installed, to start with.
My research into the matter shows that the fire codes treat power strips and extension cords as very different things, subject to different rules. Extension cords are temporary devices, while power strips can be used for permanent installations, for instance. While I found things directly addressing mixing power strips and extension cords in a chain (don’t, code violation), nothing I found specifically settled the daisy chained powerstrip issue.
