The, Heater Is 120V., Second Photo., Green Ground Wire Is On, Box., Do I Connect, New Heater To, That Wires Coming, Of, Wall? - The setup is working due to the fact every breaker pair feeds off the right panel bus leg (one attaches to l1, the other to l2). Out of your brought records, each 240v circuit is break up across the 2 breakers to do this.
You can honestly see the two buses and that there would not look like any shenanigans connecting the two of them. I eliminated the pinnacle double-pole breaker for readability. The popped dryer breaker is sincerely a single pole, as you could see the only access slot. It is apparently related to the left bus and simplest that bus.
Specifically, there are murray mh-t 30-amp breakers. These are tandem breakers and now not "slimline" or "skinny" breakers -- the two breaker switches on every aren't linked in any manner. The sort of breakers is used for the clothes dryer and the opposite for an electric powered water heater.
Additionally related is the reality that everyone now not listening to the panel setup may additionally energy off the circuit to work on it and now not realise they switched off adjoining pairs instead of change pairs of every 240v circuit, leaving a hot leg within the circuit they assume is powered down. You need matters to be fail-safe. This is not fail-secure, but is a booby lure looking forward to the inattentive or hurried. Nec frowns closely on things like this.
Murray bus backplane with interleaved palms so adjoining complete size breakers are on opposite legs. No longer genuine for the mh-t mp3030 breaker pair, each breaker inside the set is half of-width and the combination is fed off most effective one leg blade.
In the case of the dryer circuit, there may be one 10/3 nm wire, with the recent black attached to one of the sides of the tandem breaker and the new purple connected to the alternative aspect. The impartial is attached to the neutral bar. Inside the water heater case, there's a 10/2, with both the white and black connected to their respective sides of the tandem breaker. Observe how the internal handles are tied together, and that the outer handles are also tied to every other. This manner if both experience (or are turned off by way of the person), the entire circuit is close off.
