Wiring for a 30 Amp 4-Wire Dryer Circuit

Nelson, from Vivian, Louisiana asks:
Dave, in changing a 3 wire dryer outlet to a 4 wire using a 10-4 circuit, what does the connection in the breaker panel look like.

Appreciate your answer,

The connections for the dryer circuit in a main electrical panel are the two power conductors commonly the black and the red to the 2-pole 30 amp circuit breaker, and the white neutral and the ground attach to the bonded neutral terminal bar. If the circuit wiring has been installed at a sub-panel then the white neutral attaches to the neutral terminal bar, and the ground attached to the ground terminal bar.
Please be aware that I recommend that wiring and connections in any electrical panel should be done by a licensed electrician.
