“Why it's important to never plug power strips into each other”

Key points

• Plugging power strips into each other does not increase electrical capacity.
• A second strip draws load through the first, risking overheating and damage.
• Resistive heating can melt casings and ignite nearby materials over time.
• If the first strip trips a breaker, adding a second won’t solve the problem.
• NFPA warns against extension cords and daisy-chaining; use proper outlets instead.
