Text in the illustration

distribution panel
2 pole, 1 handle
tie clip
tie bar
these circuits use two 120-volt conductors (one black and one red)
we need to disconnect both to work on circuit safely
these special breakers ensure both are turned off

Generated explanation

The illustration shows an electrical distribution panel with an enlarged view of paired circuit breakers. The detail identifies three linked operating arrangements: a two-pole breaker with one handle, a tie clip, and a tie bar. These arrangements link the operation of breakers serving 240-volt and multi-wire branch circuits. The annotation explains that these circuits use two 120-volt conductors, one black and one red, and that both must be disconnected to work on the circuit safely.
