Nice Wire Size 60, 220V Collections - The setup is operating due to the fact every breaker pair feeds off the proper panel bus leg (one attaches to l1, the alternative to l2). From your introduced facts, each 240v circuit is split across the 2 breakers to try this.
What's wrong -- the foremost protection challenge right here is that with a circuit fault, most effective one of the breakers within the set may experience, leaving the 240v circuit partly energized. For example if the dryer heating coil burns thru and one quit touches floor, that aspect will experience, leaving the alternative leg hot. You without a doubt want a circuit fault to definitely power down each legs.
I need to strain that this honestly is running. Each the dryer and water heater had been wired this manner properly before i moved in and it is most effective now, years later, that i noticed what changed into taking place. It is labored great all along.
Modified to fit to new furnished statistics. Fast petey's answer carries the circuit breaker you want to install to accurate the scenario. As you could see from the breaker inter-ties, they essentially take of those breakers and manually finish off what the installer become attempting to do in a safe manner.
I ran across a panel these days that has a water heater and a dryer mounted using tandem breakers. They're no longer split both. This panel is configurable to half of a slot, meaning a regular 110vac breaker might be clipped into 2 prongs of a live bus, and there's a small plastic wall keeping apart the b aspect from the a side maintaining you from shorting the 2 110vac circuits together. But, the tandem breakers have a slot reduce out allowing you to plug into each aspects. Each facet of the tandem breaker receives its own feed from its personal prong at the buses making 220vac.
I inherited a first-rate panel box from a property owner that wasn't constantly fond of meeting the desired nec codes. As such, there are a few oddities in the panel. One such oddity is the truth that he established multiple tandem circuit breakers for use in 120/240 circuits.
