Electrical


I have a dryer hook up with a 30amp breaker on about 28 ft of 10-2 with ground (Orange wire). I have tested all componenets and it will not start the dryer under load? It stains to start. Must it be 10-3 with ground or do I need to go to 8 ga.

A new dryer circuit would need a 10/3 w/ground in it, and a 4-prong cord and receptacle.

The motor uses 120 Volts to operate, and without the proper configuration and connections it won't work properly.

Also need to make sure the 10/3 +G is properly connected to a 30A double-pole breaker with tie-bar. Can't tell from the OP if the correct breaker was used.

Both previous replies are dead on.

10/2 IS NOT legal or safe to use for this 120/240v circuit. You are using a bare ground wire as the neutral as it stands. This is a big problem.
You DO need 10/3 and a 4-wire receptacle.

The problem with the dryer running is most likely that you installed the breaker wrong. I suspect it is an FPE or GE skinny breaker. Am I right?

The 10-2 wire has the bare grounding wire hooked up to the grounding bar in the breaker box. I though it might need to be hooked to the neutral bar? Also the receptical is an three prong stove receptical. So it looks like a mess and I need another 10 gage wire in the mix, a four prong dryer receptical, dryer cord and try fishing a single wire back to the breaker box - thanks

No dice, you can't just run another separate wire alongside the cable. You need to replace the cable with the proper 10-3 w/ground. You need to replace the receptacle with the proper 4-prong, and replace the dryer cord with a 4-prong.
