			When energized, the green status indicator illuminated, indicating that the surge protector remained powered and operational at the time of testing. Illumination was present but noticeably dim.

			Testing with a receptacle tester confirmed correct hot, neutral, and ground wiring. No open-ground, open-neutral, reversed-polarity, or other wiring faults were detected.

			The documented example successfully passed basic functional testing and remained operational during documentation.

The Curtis SP-600 is a wall-mounted surge protector designed to plug directly into a duplex receptacle without the use of a power cord.

The documented example provides six grounded AC outlets and integrated coaxial-cable surge protection through dedicated IN and OUT connectors. Unlike many modern wall-mounted surge protectors, the SP-600 relies upon dual AC plug assemblies for mechanical retention and does not utilize the center faceplate screw commonly used by contemporary wall-hugger designs.

The documented example was purchased from Goodwill on 19 September 2026 for $5.00 and was subsequently preserved by the OldSurge Archive for documentation, testing, and analysis.

== Physical Characteristics ==

The Curtis SP-600 utilizes a molded plastic enclosure intended to plug directly into a standard duplex receptacle.

Six grounded outlets are arranged in two vertical rows of three receptacles each.

The lower portion of the enclosure incorporates coaxial-cable protection using standard threaded F-type connectors labeled IN and OUT.

Unlike most modern wall-mounted surge protectors, the SP-600 lacks a center mounting screw intended to secure the device to the receptacle. Mechanical retention instead relies on two sets of AC plug blades mounted on the rear of the enclosure.

The enclosure features curved ribbed side panels that project beyond the main housing and contribute to the unit's distinctive appearance.
