Physical Description

The VG307 utilizes a rectangular beige plastic housing with seven grounded outlets arranged in a single row.

A red rocker-style power switch is located near the cord entry point. The switch does not illuminate on the documented example, although its design resembles an illuminated rocker switch commonly found on surge protectors of the period. The switch motion is perpendicular to the row of outlets.

The VG307 provides seven grounded outlets arranged in a single row. A resettable circuit breaker is located adjacent to the power-cord entry point.

The documented example measures approximately:

• Length: 12.25 in (31.1 cm)
• Width: 2.19 in (5.6 cm)
• Height: 1.25 in (3.2 cm)

The attached power cord measures approximately 4 feet (1.2 m) in length and utilizes an SJT-rated jacket with three 16 AWG conductors. Cord markings indicate a 75°C temperature rating and identify the cord manufacturer as Rhythm.

The VG307 utilizes a long, low-profile enclosure with rounded end caps and a single row of seven grounded outlets.

The VG307 utilizes a grounded three-prong molded attachment plug permanently affixed to the four-foot power cord.

The housing is supported by molded feet that elevate the enclosure slightly above the mounting surface.

The documented example is finished in beige plastic and incorporates a large red rocker-style power switch located near the power-cord entry point.

The VG307 incorporates two keyhole mounting slots on the underside of the enclosure. The slot design supports installation in either horizontal or vertical orientations, providing flexibility for wall, desk, or cabinet mounting.

The attached power cord bears markings identifying it as an SJT-type cord utilizing three 16 AWG conductors with a 75°C temperature rating.

The molded support feet serve a dual purpose: elevating the enclosure slightly above the mounting surface and stabilizing the unit to prevent rocking when placed on a flat surface.

The housing is assembled using multiple screws, permitting non-destructive disassembly.

Mounting Provisions

The VG307 incorporates two keyhole mounting slots on the underside of the enclosure. The slot design supports installation in either horizontal or vertical orientations, providing flexibility for wall, desk, or cabinet mounting.

Testing

The documented example was tested for basic electrical operation and wiring integrity.

A receptacle tester indicated correct hot, neutral, and ground wiring throughout the surge protector. The tester reported normal wiring with no open ground, open neutral, reversed polarity, or other wiring faults detected.

The rocker switch successfully controlled power to all outlets. The surge protector remained energized and functional when the switch was turned on and disconnected power to the outlets when the switch was turned off.

Although the red rocker switch resembles an illuminated switch, no illumination was observed during testing.

Operational Notes

The documented example powers connected devices normally.

The unit incorporates a red rocker-style power switch. While the switch resembles an illuminated rocker switch, no illumination is present on the documented example during operation.

Condition Upon Acquisition

The documented example was acquired as part of a collection of surplus electronic equipment and showed accumulated dust, dirt, and cosmetic wear consistent with long-term use.

The unit was cleaned prior to detailed documentation and photography.
