# Low voltage only or can timer be used for 110 v

On the timer it shows 1hp 125 vac 5 amp 125 vac tungsten 20 amp 125 vac 10 amp 250 vac is this timer only for low voltage or can I use it to control lights that use  110v

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.

### I'm going to Italy. Is it dual voltage?

Italy uses 220 volts, 50 cycles alternating current (AC). If your appliance works on both 110 or 220 then IT'S dual voltage and should work. If it only runs on 110 then you will need a voltage converter to use it on 220.

### Adustments engine speed low rpm

You cannot adjust the voltage output. All generators are rated for 110-125 volt recepticals and usually have at least one 220-240 volt receptical for special appliances that require it such as water heaters, pumps, welders, air conditioners. When one of these higher draw appliances is connected and they begin to draw amperage, the gas engine will automatically increase rpm to produce enough amps. If your generator gauge is showing low voltage such as 60,80 or 90volts for example, then you have overloaded the generator and blown a capacitor, resistor or similar item.

### Pool pump breaker tripping

1) Not likely the timer is problem, unless there was fire or overheating in timer box. Use nose and eyes to inspect for signs of high heat.

2) Eliminate timer as suspect:
Move wires on timer to test if timer relays have gone bad.
Move terminal 4 to terminal 3
Move terminal 2 to terminal 1

3) Check watt rating of Hayward pump, and voltage.
1Hp motor at 240Volt draws 8 amp, and can draw 6 to 8 times that amount when starting. Up to 100 feet, should be at least 12 gauge wire and double-pole 20 amp breaker. Over 100 feet, 10 gauge wire and 30 amp double-pole breaker is best.

4) Intermatic T104 240V timer is rated 40 amps
Can safely handle 1 Hp motor without nearing heat-rating capacity of timer

5) Make sure the motor is wired correctly for 240Volts.
If motor is wired for 120, and 240 is applied, then tripped breaker can result.

### 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.

### Is the intermatic standard lamp and appliance timer..TN111C...powerful enough to start up reliably a 400 -430 watt metal halide or high pressure sodium light?? Thanks

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

### Why did my craftsman 5 hp 240 volt 125 psi air

your motor overheated from too low a voltage if theres a manual reset try this,also replace the two motor start and run capacitors on the motor body

### I want to re wire an electric motor for low volt

Look on the name plate. If it says under 'volts' 120/240 that means it's dual voltage and you can use either voltage to run.

### My hayward 1hp pool pump is running very hot to touch

Make sure the supply wire is the correct gauge for the current draw. The main reason to run on 240 volts is a smaller gauge wire and breaker than on 110 which draws close to 15 amps. For example a person using an above ground on a small extension will cause it to overheat. Make sure it is getting as much power as possible
