NSi 701B – Frequently Asked Questions

1) Will the NSi 701B timer switch fit in a standard single gang switch box?
Yes. The NSi 701B 24-hour wall switch timer mounts to a standard single gang wall plate, so it drops into an existing single-gang switch location during a retrofit. White housing, so it matches common white plates already on the wall.
2) Is the NSi 701B a single pole timer, or can it be used in a 3-way circuit?
It is SPST, single pole single throw. That means it replaces a single-pole switch controlling one load. It is not a 3-way device, so if the light is switched from two locations you need a different control.
3) Can I run the NSi 701B timer on 277V or a 240V circuit?
No. The 701B is a 125 VAC device rated 20A at 125V on 60 Hz systems. Use it on standard 120V branch circuits only; a 240V pool pump or a 277V commercial lighting circuit needs a different timer.
4) Can the NSi 701B timer be installed outdoors or in an unheated garage?
The timer itself is rated for 32 to 104 F operating conditions, so it belongs indoors, in a conditioned or protected location. It switches outdoor loads (porch, patio, pool and security lighting), but in a garage or shed that drops below freezing you are outside the rated range.
5) How precisely can I set the on/off times on this mechanical wall timer?
The NSi 701B uses a mechanical 24-hour dial with 30 minute tabs, so the smallest increment you can schedule is a half hour. Set the tabs once and the same on/off pattern repeats every day. There is no 7-day or astronomic (sunset tracking) scheduling on this model.
6) What load can I put on the NSi 701B, and will it handle a pool pump or a bank of exterior fixtures?
Rated 20A at 125V, which covers a full 20A 120V lighting branch circuit, so a run of porch, patio or security fixtures is well within it. For a pool pump, check the motor nameplate: it has to be a 120V motor and its running and locked rotor draw has to stay inside that 20A 125V rating, and the switching is SPST so only one ungrounded conductor is broken.
7) Do I need a neutral wire in the box for this mechanical timer?
The 701B runs a mechanical 24-hour clock motor on 125 VAC at 60 Hz, so the clock needs a continuous supply to keep time, not just the switched leg. Confirm you have a neutral available in the single gang box before you pull the old switch.
8) What part number do I order for the NSi white 24-hour wall switch timer?
Order NSi Industries 701B. That is the manufacturer part number for the white, 24-hour mechanical wall switch timer rated 20A 125V SPST. It is a single configuration, no finish or voltage options to specify.
