Electronic – Is this a correct way to route current away from breadboard

breadboardservo

I've recently grown interested in electronics and robotics, so I wanted to move my contraption using a servo motor. A 555 chip creates a PWM signal for servo for positioning, and I control the servo with a variable resistor.

I'm sure it will be able to move my contraption with ease, but I'm not comfortable putting 3 A through the breadboard (which would happen if the servo stalled).

Would something like the following work?

I believe this would route power required by the servo around the breadboard so breadboard would only work with the current required for controlling the servo motor, for creating PWM.

You are correct, this will avoid passing a heavy current through the breadboard.

Make sure the wires that go from the power supply to the motor are capable of carrying the maximum expected current. Ideally take these wires separately all the way back to the power supply and run another pair of wires from the power supply to the breadboard.enter image description here
