It shouldnt matter what orentation the wires are,each one is 110 volts from both feeds, together they make 220 volt.the differant colors are just for idenification of the cable at each end

Ben, you are on the right track. To upgrade the breaker, first look at the main house breaker panel and determine if allowing more current through main breaker will be taxing it too highly (will 20 more amps exceed my main breaker limit...what is the main breaker current trip at?) Then look at the wire size leading away from the 40 amp breaker to outside. If it is 6 gage copper or 4 gage copper-clad aluminum wire, you are ok to upgrade. Any smaller wire size could be unhealthy.

SOURCE: wiring a heat strip

DO YOU MEAN FEED IN OR FEEDING HEATING ELEMENT . I ASSUME YOU MEAN TO FEED FROM PANEL THE ANSWER IS YOU MUST RUN 2 CIRCUITS OF 3-cond #6 copper to unit connect the feeds to one breaker and the other circuit to the other breaker the neutrals connect to lug provided or purchase them and frame gnd to case , i would not recommend anything except copper as most mfg do not rec aluminum because on the heating and cooling of the unit and conductors

SOURCE: I have a 220v 100

your a/c uses the blower motor from the heater to distribute air check for loose wire connections that will raise amperage and also make sure you have the right size wire to each unit 40 amp should have 8 awg(copper) wire and 60 shouldbe 6 awg i think if the wire is to small=heat= higher amperage

SOURCE: I have 60 amp circuit breaker on my electrical a/c

You're unit is a 31/2 ton according to the numbers.Normally, breakers will only be in a half way posistion when tripped. Yes, under most conditions, the fuse will blow before the breaker trips. I have seen this many times, the breaker may be weak, burned, loose wires and so tighten wires, check the condition of the breaker.It sounds like the breaker even though it is 60 amps, is the problem and you should replace it with out hesitating. This will solve you're problem. When you pull the breaker out, look at the metal clips that snap in on the buss bar to see if they have been overheating.And the buss bar its self. You will know. I am sure this will take care of you're problem. Good Luck,

SOURCE: hello, my heat pump is a 4 ton unit, it heats ok

Hello Jack,

Let me see if I have this right. Your heat pump keeps triping the breaker that is going to your airhandler. The Heatpump is on its on breaker and can not trip the breaker on your air-handler. However, the 40 amp breaker is to you heat pump its self (the outside unit). The thermstat is not the porblem as all it does is call for heat or cool. The problem can be one or a cobination of three things the contactor, the run capcitor or the breaker is weak.

The first thing I would do is replace the breaker as if it has tripped more than twice it needs to be replaced. Then I would look at the contactor, it is located underneath the service panel it will have some low voltage wires on the sides and a black and white wire running to it from the disconect box. If you notice the contacts are chared (little copper points in the middle of the contactor) I would replace it. If the contactor looks good I would remove the capcitor (carefully not to touch to contacts at once as they hold a charge) and take if to the local parts house and have it tested.

I hope that I have asnwered you question and you are able to take care of the problem. Thank you for using FIxya and do not hesitate to ask more questions.

Justin

I have the right circuit breaker in the hvac tempstar unit i cant remember which wires to re connect 2 black and 2 red


Connect to what the breaker or unit? If you switched the breaker and pulled 4 wires from a 2 pole breaker then logically the two blacks go together on line 1 and two reds go together on line 2. This is according to the color code.

What size wire and how does it hook to thr unit rpkb-036jaz


Look at rating plate on side of unit for Volts, Amps, Watts.
Volts x amps = watts.
If unit is 240Volts, then you need double-pole 240Volt breaker
If unit is 8500 watts at max power, then 8500 watts divided by 240Volts = 35 amps.

What size breaker for 35 amps?
When electricians figure load rating for breakers, they use the 80% rule.
40 amp breaker x 80% = 32 amp safe maximum load for 40 amp breaker. Use 8 gauge wire with 40 amp breaker.
50 amp breaker x 80% = 40 amp safe maximum for 50 amp breaker. I use 6 gauge wire with 50 amp breaker.
60 amp breaker x 80% = 48 amp safe maximum for 60 amp breaker. Again, use 6 gauge wire with 60 amp breaker.

How to connect wires to unit.
First of all, all outdoor HVAC units require power cut off located next to unit.
This lets the mechanic, or service tech turn power off to work on unit, even if the mechanic does not have access to main breaker box.

Next, open unit to see where wires connect.
If unit has wires, then connect both hot wires from 240 breaker to the wires inside unit. Connect bare ground wire to green ground screw.
If unit has terminals. The terminals will be labeled L1 L2. Connect each hot wire from 240Volt breaker to either one of the screw terminals. Then bare ground goes to green ground screw.

Copy following links for basic illustrations connecting wires to terminals, and to breakers, and selecting wire size.

1 or 2 circuits to create 2 phase?


How to explain this? your new drop in unit will require a 220v circuit capable of a specified amount of amps. Typically 40, 50 or 60. Should be noted in the manual and on the unit itself. If your original oven and cooktop were electric, then each one was probably hooked up to a 220v circuit. The problem is figuring out how many amps were supplied for each. The simplest way is the go to the panel and find the breaker for the old oven and cooktop and read the numbers (or amps) on the on/off switch. If either breaker has a number the same or greater then the drop in unit says it requires, then your all set. If the drop in unit says it requires 52amps and one of the breakers says 60 on it, your fine. If the drop in unit says it requires 44amps and the breakers are 30 or 40, then you got a problem. Usually a breaker is installed that is the maximum amps allowed for the size (thickness) of the wire connected to it. You CANNOT connected a 50a breaker to wire only rated for 40a. Note the size difference of wire connected to a 20a breaker with wire connected to 40a breaker. If the drop in unit requires more amps then the original units used, then a larger wire will need to be ran from the panel to the drop in unit (Not cheap). Now if the original oven used a 30a and the original cooktop used a 30a, then its possible ( 80% of electricians wouldn't do it because of liability problems) to use both wires together to create 60amps, but both wires (actually a total of 6 wires, 2-120v wires and 1 ground wire from each outlet) would need to be in the same outlet box for the drop in unit connection.. I could (and probably should) try to explain more, but I'de probably just confuse you more. GOOD LUCK!

Trying to install a 30 amp breaker into a ge powermark gold 200


Hello, First, you need to determine if you are installing a 220 or 110 vac circuit breaker. The 220 is a "double pole" and will have (on the underside) 2 tabs for each 110 phase on your breaker box. It will also usually have a double switch tied together. A single or 110 breaker will just mount to one of the "hot bars" on the breaker box. Again, look at the underside of the breaker. Just remember you need 2 wires (usually a black and a red) for 220 and only one wire (usually black) for a 110 single. The neutral shouls tie to the neutral bar on the box (where all the white wires are connectoed to)

Of course, use extreme caution and insulating gloves when working on a circuit breaker.

Hope this helps and good luck with it. Gary

Wireing three units together


yes, you did a good job. Sounds like you paralled them. Which is right buuuut what size are these heaters. Add the wattage of all of the heaters and divide by 120 and that is how much current you will be using. On a 20 amp breaker you can only pull 16 amps safely. I think you will be way over unless the heaters are 600 watts each. You are allowed 1800 watts on a 20 amp circuit.
