My limited research indicates this heater is designed for USA electrical systems. That would mean single phase, 240/208 volts, 60 Hz. The drawings I reviewed shows a 2 pole, 240 volt breaker feeding each heating circuit. That means no "neutral wire" goes to the heater and therefore no 120 volts is needed. This is good. Kenya's system is single phase, 240 volts, 50 Hz. The heater should work reasonably well on the African system. Connect the power just like you would in the US.

Trying to wire a 220 volt furnace in a three phase breaker box

normally in three phase applications all three wires have a 120 volts each on them and normally the electrician will lable either by tape or put in the middle slot whats called a high delta leg which has a little more power going to it... if no tape then the two outside wires in the 3 phase pane can be connected to the furnace. just check across them at 3 phase panel prior to connecting to make sure your getting 220-242 volts hope this helps you out ...good luck

I bought a Fostoria 3060-3 used heater. My question is can I hitch that up with a 220 line instead of a 480? I might need a manual sent to me(I would pay for one) if no one is sure if that is something...

What you bought is an industrial voltage heater and I purchased one last year as well. According to the manual and the model number you give it translates to 30 kilowatts 60 is 600 volts AC the -3 is three phase. This is only for three phase 600 volt operation, and no you can not wire this heater single phase it will not work period. Even if you do wire this thing at 220 volts single phase double pole there would not be enough voltage to run the fan let alone heat the elements. Can you return the heater? By the way Fastenal is the distributor for these that is where mine was purchased. All of my information is out of the manual that I got with my purchase of a Fostoria FES3048-3.

How to wire three-phase heater -model-berner mark 1 56e i have 220&110 the heater has three wires

If this is in a home or garage you can not wire three phase as residential wiring does not have three phase, commercial buildings have three phase. Not saying it is not possible to get three phase to the house, but this could be quite costly. My suggestion is to purchase a 220 volt heater. Do not destroy the packaging it came in so you can pack it up and return it. Sorry for the bad news.

I have a Hatco c-6 and it is set up for 208 volts 3 phase hook up and the terminals are labled 1-2-3 in the heater.. I have 3 phase and the wires are from the 3 phase panel to the heater..the wires are...

Thanks for your reply. The order in which you connect the wires 1-2-3 does not matter, all three terminal block screws will accept any one of the hot wires from the breaker, one hot wire per each terminal screw.

I have a new water heater, and the hook up terminals are labled 1-2-3 are they hooked the same as in the panel 1-2-3 ?

No. You have to find out if you have 3 phase or single phase power. If this is a new unit you will find a wiring diagram inside the front cover. 3 phase power has 3 "hot" wires. Single phase has 2 "hot" wires. There is a big difference when you hook it up wrong. I don't know if this is a new installation or if you are replacing an old one. The terminals are numbered for 3 phase. If you look in your breaker box, 3 phase 208 will haven a breaker with 3 spaces hooked together by one bar. Single phase will have two spaces hooked together by a bar. So if the breaker kicks out it will flip all 3 space on 3 phase or 2 spaces on single phase. If you already have wires to the location of the booster heater, you may have to use single phase if that is all that is at that location. If you have single phase power you will have to look at the wiring diagram and you will see the terminal block represented for both single and 3 phase. Normally running from the terminal block will be six wires marked 1 through 6. The wireing diagram will say something like "for single phase put 1,3,5 on terminal 1 and 2,4,6 on terminal 3. Leave terminal 2 out all together. Of course at this point your 2 hot wires will go to terminal 1 and 3. There are other considerations as well. With 3 phase the circuit wires will be smaller gauge and may not carry the current you need for single phase. This is a booster heater. You need to hook up your hot water line to go into the heater and the boosted hot water to your appliance. It will not work to heat your water for other purposes. It is meant to take 140 degree water and boost it to 190 degrees. Good luck, hope this helps

Wiring an electric water heater

Hello,You are correct! Black/blue=black & Yellow=white 220volt single phase power.There are 3 wires for 3 phase power connection NOT the case in a home.Also an "off peak"timer option would use (black) only controlling the bottom element and (blue) controlling the top element.

I have a heater that can work on 3 phase or monophase. I know because there is a screw that can be turned to switch between the two. The problem is that it has been wired for 3 phase with 4 wires: earth,...

2 x black go to each leg of 230 power. Neutral goes to a neutral point, and earth goes to an earth ground point. While you can tie earth and neutral together (they are in the breaker panel anyway) it does not meet some codes to do this when the appliance provides for separate connections.

Wiring for a dayton 3Z967A

Although your model number does not register at, it sounds like it may be a granger item. I find refernece on google that it may be a ( 14.5CFM@175PSI 230-460V 3 PHASE, 80 GALLON) shop type compressor. Thus to wire this unit you would need to look at the info sticker on the motor to determine if it actually needs three phase. If there is no refernece sticker on the motor, then call the grainger 1-800 number which is found at the above mentioned web address and speak to a rep that will fax you what info they have. Many times the information about the motor will be found by looking for a grainger part number for the motor only instead of the grainger # for the whole unit. Also the motor may have been changed. If you determing that its three phase and you have three phase available please email and I will try to help with wiring, should be easy. I will need all the wire labels such as (L1, L2 and colors.) Three phase motors have many wires that are tied together to make three lines. Please tell me how they are bundled. Good Luck with grainger.
