Siemens 30, Double-Pole Type, 22KA Circuit Breaker - Word how the inner handles are tied collectively, and that the outer handles are also tied to each other. This manner if both trip (or are became off by using the user), the entire circuit is close off. Specifically, there are murray mh-t 30-amp breakers. These are tandem breakers and no longer "slimline" or "thin" breakers -- the 2 breaker switches on every aren't linked in any manner. Any such breakers is used for the clothes dryer and the alternative for an electric water heater.
The setup is working because every breaker pair feeds off the proper panel bus leg (one attaches to l1, the alternative to l2). Out of your introduced information, every 240v circuit is break up throughout the two breakers to try this. Changed to suit to new supplied data. Speedy petey's solution includes the circuit breaker you need to put in to accurate the state of affairs. As you could see from the breaker inter-ties, they basically take of these breakers and manually end off what the installer become attempting to do in a secure way.
This seems all styles of wrong, even though. It's nonetheless a single pole breaker, even though there are two 120v circuits coming off it. It seems like if this turned into k, that i might hear approximately using a tandem breaker as a space-saving slim 220v breaker... But i've seem not anything. I have read that tandem breakers may be installed to both feed power from one leg of the bus bar or from two extraordinary legs. If it's the latter to your case, then you definitely'd be getting 240v in the end. Check the terminals of the breakers in query (or check on the shops where your home equipment are plugged in) with a voltmeter, if you haven't already, and verify what is truly being fed for your home equipment.
I inherited a first-rate panel box from a homeowner that wasn't always fond of meeting the specified nec codes. As such, there are a few oddities inside the panel. One such oddity is the fact that he hooked up more than one tandem circuit breakers for use in 120/240 circuits.
