Can I use these two breakers to protect one 220V (40 amp ) circuit? And can I buy a bar to connect the two switches so they switch on and off together?

No. You can't add the amp rating to equal 40 amps. Each leg of the breaker will only handle 20 amps. Your existing configuration has 40 amps on each leg. A 20 amp double pole breaker still only handles 20 amps for the circuit.

Yes. They should protect all the circuits. Not sure you need a bar since they should trip if there is a strike.

Yes, I used the two breakers to protect my 220v Water Pump. I connected the two breakers together by placing a small bolt through the hole in each breaker, so they switch off at the same time. Used a small tie wrap to secure the bolt. Serves the same purpose as a bar.

You have to be careful with 220 and 40 amps. My recommendations would be to check with Lowes or Home Depot. They normally have people that manage the department that can give you advice and the right product. I have a garage heater that requires two 40 amp circuits. I purchased a single (double wide circuit breaker) that has one bridge that turns the circuit on or off. Best to check with someone that deals with electric on a daily bases. Mike-ee

Yes you can use the normal breaker and wall switch. Any that has a metal reflector and is rated for a 250 watt light(important so it won't melt).

'different circuit' is ambiguous. I have a large house with two phases coming in (allowing for 220V appliances). The units work without issue as long as they are both on the same 'phase' - even if controlled by different circuit breakers. But if the two units are on separate phases then I can't imagine they would work since there is no direct connection between the two phases (other than by 'neutral') - but I haven't yet specifically tried this. So far, the units have worked on every outlet I've tried.

Hard to tell from your question exactly what you are planning to do.It certainly can be used to protect one load on a double pole circuit but it should be connected through a breaker on each line.See the instructions at this link-http://www.intermatic.com/~/media/Intermatic/Documentation/Surge%20Protective%20Devices/IG%20Series/IG1240RC3%20Instructions.ashx

You might able to used this timer for both if you hook it up correctly. It is advisable to use a multimeter to check the output of each of prongs to see if it output 110v instead of 220v. There is instructional manual that come with these timer. If I remember correctly there is two 110v prongs wire for 220v machine, you can split one of those 110v prong to generator and pool pump also. It best to double check to see if the timer give out correct voltage.

Pretty simple if you have two adjacent slots in you circuit breaker box so that it will accommodate a 20 amp 220 circuit breaker.

I can tell you that they provide a 30 AMP fuse to protect the circuit. Hope that helps!

This type of question should be addressed by an electrical specialist. Not sure the switch is rated for 220 volt service. Certainly that's not how it is usually used. 20 amps at 220 volts is a fairly heavy load.

Ours is wired to use two switches. Not an electrician, but I would imagine you could wire them both to one switch if desired.

I think 30310a uses proprietary breakers and q310a uses off the shelf 1" breakers so you could swap how it comes to something that fits YOUR configuration. I bought q310a and swapped out the double pole 220 breakers for 10 110 breakers because I had no need for 220 amp breakers in my situation. I think in 30310a you're stuck with how it is. I don't think one is better than the other in Florida or anywhere else!! The previous answers seem to confirm.

I found the book that came with the unit was very helpful. Another way is looking at the major appliance ratings you are going to use the switch for. Getting it reasonably close will work fine. If you have 2 things that are hooked to 20 amp breakers split them wiring them to the red terminals, etc. Best I can do, hope it helps.

i am using a 60 amp breaker on the 220 v circuit. at 120 v the cutter will kick out a 20 amp breaker if turned up over half power. i haven't tried using it on a 30 amp/120v circuit. But have used it at full power on my 220 v circuit with no problems.......

Although I'm not a professional electrician, I would say NO as the system requires 3 - 40amp 220/240V circuit breakers (120Amp total).

Yes....... 240vac is the max.Your main concern is that you have the space in your electrical box for 2ea 2-pole 40amp breakers and that your service can handle extra 80amp load.

You just choose what circuit pluse the common bar. you want to use and use those breakers. Ya gotta follow the instructions but the wires are numbered and it's actually not hard.

I have used solid state relays for heavy loads. Make sure your electrical load does not exceed the capacity of the relay. Two relays should be used for a 220 VAC power source. One for each power leg. Turning on both relays at the same time is no problem. On the other hand, I'd prefer using a 2 pole mercury relay that usually has a 120 VAC coil. Grainger carries such a unit. example: Item # 12N674 www.Grainger.com

I used 2 110 breakers that are next to each other a black wire in each one, white wire to ground. You can use a dedicated 240 breaker if you wantbut 2 110 breakers next to each other will do the same thing. I called the seller and that the way he said to hook it up.Jay Trumbojt61@hotmail.com
