Wire Gauge 40, 220V Circuit - Particularly, there are murray mh-t 30-amp breakers. These are tandem breakers and now not "slimline" or "skinny" breakers -- the two breaker switches on each aren't linked in any manner. Any such breakers is used for the garments dryer and the opposite for an electric powered water heater.
What's incorrect -- the primary safety challenge right here is that with a circuit fault, best one of the breakers inside the set may journey, leaving the 240v circuit partially energized. For example if the dryer heating coil burns through and one cease touches ground, that facet will ride, leaving the alternative leg hot. You truly want a circuit fault to completely energy down each legs.
I ran throughout a panel these days that has a water heater and a dryer established using tandem breakers. They're no longer cut up both. This panel is configurable to half of a slot, meaning a regular 110vac breaker might be clipped into 2 prongs of a stay bus, and there's a small plastic wall isolating the b facet from the a facet keeping you from shorting the 2 110vac circuits collectively. But, the tandem breakers have a slot cut out allowing you to plug into each sides. Each side of the tandem breaker receives its own feed from its very own prong on the buses making 220vac.
Inside the case of the dryer circuit, there is one 10/three nm wire, with the recent black attached to one of the sides of the tandem breaker and the recent red connected to the opposite side. The neutral is attached to the neutral bar. In the water heater case, there is a ten/2, with each the white and black attached to their respective aspects of the tandem breaker.
The setup is operating due to the fact every breaker pair feeds off the right panel bus leg (one attaches to l1, the opposite to l2). Out of your introduced information, every 240v circuit is split across the two breakers to do this. Modified to fit to new supplied records. Speedy petey's answer carries the circuit breaker you need to install to correct the state of affairs. As you could see from the breaker inter-ties, they basically take two of these breakers and manually finish off what the installer became attempting to do in a secure manner.
