Intermatic GM40AV-W – Frequently Asked Questions

1) Will the Intermatic GM40AV-W work on a 277V circuit, or do I need a different model for 120V?
One model covers both. The GM40AV-W is an autovoltage time switch rated 120-277 VAC, 60 Hz, so the same unit works on 120V, 208V, 240V or 277V single-phase control power. That is the reason to stock it instead of voltage-specific clocks across a mixed facility.
2) Can one Intermatic GM40AV-W time switch control two separate circuits?
Yes. The GM40AV-W is DPDT, giving 2 normally open and 2 normally closed contacts rated 40A, so you can switch two loads on the same schedule or run one load on and one off at the same time point (for example a fan on while a damper circuit drops out).
3) Is this an electronic or a mechanical time switch, and will it hold its schedule in a power outage?
The GM40AV is an electromechanical time switch, not a digital one. The schedule lives in mechanical trippers on the dial, so the program itself cannot be erased, but the motor-driven clock does not advance while power is off, which means the time of day needs resetting after an extended outage. If you need carryover timekeeping, specify a time switch with a battery or capacitor reserve instead.
4) How many on/off events per week can the GM40AV time switch be programmed for?
Up to 42 ON/OFF operations per week on a 7-day dial. That is enough for multiple cycles a day on every day of the week, which is what aeration and ventilation schedules usually need. Scheduling is set with mechanical trippers on the dial, and they are captive so they cannot fall off and get lost during a changeover.
5) What enclosure space do I need to mount an Intermatic GM40AV-W time clock?
Allow for a gray enclosure measuring 8.875 inches high, 6.609 inches wide and 3 inches deep. Plan the mounting location so the clock face stays readable and the ON/OFF/AUTO override lever and the power and status LEDs are reachable without opening anything up.
6) Can maintenance staff run the equipment manually without changing the time clock program?
Yes. There is a three-way ON/OFF/AUTO manual override switch, so a tech can force the load on or off for service or testing and then return the lever to AUTO, leaving the tripper schedule untouched. Power and status LEDs confirm which mode it is in at a glance.
7) Is the GM40AV-W suitable for exercising a standby generator on a weekly schedule?
Generator exercising is one of its listed applications, along with aeration, air movement and ventilation, refrigeration merchandisers and septic treatment. With 7-day programming you can set a fixed weekly run, and the DPDT contacts let you signal a second circuit at the same time.
8) What is the part number and country of origin for the Intermatic 40A autovoltage time control?
Order it as Intermatic GM40AV-W, a 40A autovoltage general purpose time control in gray. It is made in Mexico.
