Q120 20-Amp Single Pole Type QP Circuit Breaker, Siemens Q Breaker, Amazon.Com - The setup is operating because each breaker pair feeds off the right panel bus leg (one attaches to l1, the alternative to l2). From your brought records, each 240v circuit is split across the 2 breakers to try this.

Inside the case of the dryer circuit, there may be one 10/three nm wire, with the new black attached to one of the sides of the tandem breaker and the new pink connected to the alternative aspect. The neutral is hooked up to the impartial bar. Inside the water heater case, there's a 10/2, with each the white and black attached to their respective aspects of the tandem breaker.

What is wrong -- the foremost safety concern right here is that with a circuit fault, handiest one of the breakers in the set may also experience, leaving the 240v circuit partially energized.

This manner if either journey (or are grew to become off by way of the person), the whole circuit is close off. Also related is the fact that every body no longer paying attention to the panel setup may additionally power off the circuit to work on it and now not recognize they switched off adjacent pairs as opposed to change pairs of each 240v circuit, leaving a warm leg within the circuit they think is powered down. You need things to be fail-safe. This is not fail-safe, but is a booby entice watching for the inattentive or moved quickly. Nec frowns heavily on things like this.
