The specs you wrote above are for high voltage.

125 vac = 125 volts alternating current = high voltage
250 vac = 250 volts alternating current = high voltage

110 v = 110 volts alternating current = high voltage

110 v is just another name for 125 vac -- it's called the "nominal" voltage.

So, the answer is yes, this timer can be used for "110 volt lights".

A 60 watt incandescent bulb pulls 1/2 amp when connected to 120 volts -- the spec for your timer looks like is 20 amps @ 125 volts tungsten (tungsten is the filament in incandescent light bulbs) --

I say looks like 20 amps because it's not clear which amperage goes with which voltage. Here are both calculations:

- 10 amps divided by 1/2 = 20 bulbs

- if it's 20 amps: 20 amps divided by 1/2 = 40 bulbs.

1 hp= 750 watts
125 vac = 125 volts alternating current, wall outlets
5 amp= 5amps

125vac x 5amps= 625 watts

a timer is a switch with a clock on it. just like a switch in a lamp cord.

Geyser timer stopped working

Check circuit breaker.
Click fully off and then back on.
Check for burned smell at breaker or loose crackling sound that says breaker is bad.

Reset timer. Then Reprogram.

This timer has a non-replaceable internal rechargeable battery.
If battery has gone bad, then timer is defunct.

Use manual override button to turn timer ON-OFF.
Then test across terminals 3 and 4 for 240Volts.
Turn timer OFF, and test across terminals 4 and 5 for 240Volts
If no voltage shows then timer does not have output.

If test shows 80% undervoltage, that can cause load not to activate, depending on type of load.
Have electrician check for voltage issues at power company transformer.

Unknown what load timer is connected to.
Max load for this timer at 240 volts is 3680 watts, 16 amps.
Motor load is 230 volt 8 amps.
Check label on load for watt or amp rating.
Volts x amps = watts
Watts divided by volts = amps

I would like to know what wattage can the SS8 series handle??

Intermatic SS8 Instruction Manual says:
The timer can control incandescent lights, fluorescent lights, flood lights (PAR lamps), stereos, or appliances such as an air conditioner. The timer can also control many loads 12 to 277 VAC and 12 to 28 Volts DC.

Intermatic Load rating pdf shows SS5 at 500Watts and no HP rating.
Load rating pdf shows SS7 and SS20 rated for 15Amp, 120V-1HP, 240V-2HP.
Load rating does not show SS8, but since SS8 manual shows 'appliances and air conditioner,' and same load parameters shown for SS7, then Amp and HP rating would have to be same-similar to SS7.

I bought timer model #402A. It says 1250 watts tungsten rated. Here is my question: I have a demhumifier that draws 1800 watts-can I use the timer and what does 1250watts tungsten mean? Thank you.

1250 watt tungsten: Tungsten is the tungsten filament in light bulb.
So 402A timer is rated for light bulb only and not dehumidifier motor load.
1800 watt dehumidifier will burn 402A timer, and could start a fire.
I suggest Intermatic heavy-duty appliance timer HB113C:

I have a t40404r. one timer has been unused. i attempted to wire it up this week. the manuel switch works when i flip it to on but the timer/wheel/motor will not work. i have two 110 wires attached to...

If it was me the first thing I would do is to verify that you have the proper voltage to the timer that you are hooking up. I would also take the timer that is working and replace it with the one that isn't and see what happens. This may tell you that the timer is bad. I would put the working timer in the place you are trying to put your new one. This can tell you if your power supply is right. Hope this helps. Thank you

intermatic makes a timer for window air conditioners its the same design and only a few bucks more is more robust . I just tested my 175 mh lamp and it draws 1.9 amps on start up the amps go down after it starts.. harbor freight has a cool timer also (cheap) But please try to buy the timer made in the good old USA ....Jay

Timer not working Malibu ML88T Power pack

there are multipul 12 timers on the market BUT if you use a 12 volt power pack designed for a car radio display or even a simple 12v 5 amp laptop power suply and a cheep outdoor timer or cheeper indoor timer and run wires inside you can add lights
remember theise lights are low voltage and if you change the bulbs out you can really strech out the amprage too
low amp led automotive bulbs are a great invention they draw mili amps and use 12 volts
i converted my noma moonrays to a laptop power supply and added 30 more to a single string so i curently have 50 lights on 1 power suply pulling aprox 4.5 amps out of a 5A power supply i used led bulbs and simple moma cord now i can light the whole back yard with 1 ps and it's really bright if i use the led headlamps mounted under the soffit on the house
