Hello.I switched over from a gas dryer to an electrical dryer in our home. I ran 10/3 wire from a dp 30A breaker to a 4-wire recaptacle for the dryer.When I turn on the dryer, she spins but no heat.When I checked the outlet, each hot wire to neutral gets 120 volts but between the two hot wires I do not get 240. I then went to the breaker and checked there. Once again 120 from each of the hot wires to neutral, but no 240 volt reading from one hot wire to another. What would be the problem?In fact, when I check any two hot wires on the breaker I do not get 240 volts. Why? I tried swapping out the 30 amp breaker for another one in the event that it was faulty, but alas, still no 240 volts.
To me it seems like you may have bought a 30amp twin breaker which plugs on only one side of bus bar. Take breaker out and see if you only have one clip that goes to bus bar. If you have 2 clips, are there 2 bus bars there to clip on? Maybe you are at lowest part of panel bus and there is no bus bar at bottom of one side of breaker.
Check across the bus bar (where the breaker plugs in to the panel) see if it has 240 volts. This is the bar that the breaker plugs in to. If you do not have 240 volts across this then check the line side of the main breaker (where the wires terminate at) see if you have 240 volts across this. If you have 240 on the wires that attach to the main and do not have 240 across the bus bar you have a bad main breaker not giving you 240 volts. You may try to re set it and see if that does the trick. If you check the line side if the main and do not get 240 volts then you should cal an electrician Hope this helps
Are you sure that your incoming service is 240v? It is possible in some older homes that the service is only 120v. Check the two hots at the top of your panel that connect to the bus bars.
You need two breakers for 240.
