can this time be used on a 3000 watt , 240 volt,40 gallon hot water tank?

I'm using it on a wall mounted that's rated at 1,480 watts. I believe this model is only rated for 1600 watts. Check Intermatic's website for another model with a higher rating. It may be discontinued so you'll have to find a used one like i did. Hope that helps.

According to the product specs it will handle 5000 watts. We used it on a 20 gal 240 volt water heater with no problems.

not legally...the timer is rated for 40 amps. 40 amps X 240 volts = 8800 watts. to boost the wattage to 9300 would be a fire hazard. look for a 50amp timer.

I wouldn't recommend this for that size tank. Unfortunately I couldn't get mine to work, the tank would have to be at least 30 gallons to use it correctly

This switch is rated to switch 2400 watts of power at 120 Volts. If your water heater has an element that is less than 2400 watts, and runs on a 120 volt circuit, yes you can use this. It is not likely that your water heater meets these requirements. You can, however, use this switch to switch a relay that is rated to turn your water heater on and off. An inexpensive example of this is the Packard C230B. It will switch 220 volts up to 6600 watts and has a 120 volt coil. This is a mechanical contactor. You can also look for a solid state relay that will be quieter and last longer, but cost more. This switch is rated to switch 2400 watts of power at 120 Volts.

No, the total wattage exceeds 3000 watts. You cannot put more more than 22 volts on any thermostat and 3000 watts exceeds 22 volts. Personally, I would not put 3000 watts on a sinlgle thermostat. 2500 is the maximum I would advise. I am, however, not an electrician, but I have years of experience knowing what I am doing, utilizing basic principles of safety and common practice. Hope this helps! I do love these heaters!

I'm not sure, I have a 250 watt for 90 gallons which I am using in an outside pond - totally under water. And it's doing great. You really need to call a pet shop for the answer - sorry. Even if the wattage is overkill, it's oK ; it will not come on pass the setting you set. So if you set it on 76 degrees and the water in your tank is 78 degrees it just won't come on.

I don't recommend 30 Gallons tank. I bought this for 10 gallon tank. It was not enough.And I found a problem. Connection is weak.(from light parts to AC adaptor)

Yes, these require 240v wiring. Use a 40 amp circuit because this heater draws about 32 amps.

Yes this is a 240v heater, if you want the max heating btu it will take at least a 40 amp dedicated circuit.

It should work if you have enough room in your tank. You need to know the amperage and voltage that your electronic system will take.

No, this is for 220, sure saves money on your electricity. Set timer to heat water only when you need it.

A 40 Gallon should have a 200 watt heater... it's 5 watts per gallon is the normal requirement

No I don't believe so.The tank inside is too small for this kind of frequent usage and it's rated 500 watts.

I would recommend finding some higher quality heater for your 300gal tank. You could find a 1000watt heater or just run 2 heaters

It probably won't even fit, but even if it does it would overheat one gallon before the thermostat could shut it off. A 25 watt heater is really meant for a 5 gallon tank or better (3-5 watts per gallon is the general rule). Small volumes of water usually don't provide enough water circulation for heater thermostats to function properly.

I have a Bradford White 40 gal heater3500w-4500w and the element fit just like the old one. I reccomend getting the socket tool to remove and install the element. I also replaced both elements. I have hot water again like it was new. I also found out that you need to drain the tank every 2-4 months to prevent mineral build up. That is what caused mine to fail.

All it requires is an outlet, mine runs 365/24 until it stops. My is in a 15 or 16 gal so it would be fine.
