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 a magnified view of paired circuit breakers. The detail identifies three arrangements for operating paired poles together: a two-pole breaker with one handle, a tie clip, and a tie bar. The annotation explains that 240-volt and multi-wire branch circuits use two 120-volt conductors, identified as black and red. Both conductors must be disconnected to work on the circuit safely, and the illustrated handle arrangements ensure both are turned off together.
