Eight outlets with 25 foot cord

The Tripp Lite TLP825 is a 120V AC surge suppressor built for home and office environments. It provides eight NEMA 5-15R receptacles spaced to accept three transformer plugs without blocking adjacent outlets. A single illuminated power switch controls all outlets. The unit mounts via keyhole slots on the back.

15 amp circuit limits total load

The suppressor connects through a 25 foot, 14 AWG cord ending in a NEMA 5-15P plug rated for 15 amps. Continuous draw must stay at or below 1800 watts to avoid tripping the branch circuit breaker. EMI/RFI filtering reduces line noise by up to 40 dB across the protected outlets.

1440 joule rating defines surge capacity

The AC suppression rating of 1440 joules determines how much transient energy the device can absorb before its protective components degrade. Clamping voltage is 150 volts RMS across full normal mode and common mode paths. UL 1449 and UL 1363 certifications confirm compliance with safety and performance standards.

Questions about this item

With 8 outlets and a 25-foot cord, how many transformer plugs can I fit without blocking other sockets?

The strip provides room for 3 transformer plugs without blocking the remaining 5 outlets, so you can connect bulky adapters and still use every socket.

What does the 1440-joule rating actually protect in a real setup?

A 1440-joule rating means the unit can absorb up to 1440 joules of surge energy across all three protection modes — hot-neutral, neutral-ground and hot-ground — before the MOVs degrade.

The cord uses a NEMA 5-15P plug on a 120 V circuit — what load does that cap in practice?

The NEMA 5-15P plug and 14 AWG cord limit the strip to 15 A continuous, which equals 1800 W at 120 V AC.
