5 Reasons Not to Daisy-Chain Power Strips and Extension Cords

Every connector adds resistance Each connection in a daisy chain increases electrical resistance, which generates heat. That heat can melt insulation, trip breakers, or start fires.

Extension cords aren’t built for continuous use Extension cords are temporary solutions, not permanent wiring. Plugging a power strip into one asks a short-term product to handle long-term demand.

Power strips aren’t designed to plug into each other Power strips are meant for wall outlets, not other strips. Chaining them makes it easy to exceed the first strip’s amp rating without noticing.

Electrical codes explicitly forbid it The National Electrical Code bans daisy-chaining power strips and extension cords. This isn’t a suggestion—it’s a safety rule based on voltage drop and overload risks.

There’s always a safer alternative If you need more outlets, buy a single heavy-duty power strip rated for your load, or hire an electrician to add permanent outlets. Spending a few extra dollars beats risking a fire.
