The simple answer is that the breaker is tripping because two much current is flowing through it. Here's a list of some possible causes for over-current: Faulty wiring may be partly short-circuiting Faulty appliance is drawing too much current Too many devices on that circuit, in total drawing too much power I would start by proving to yourself that ...

I have to agree with Ecnerwal here. Electric Tankless WHs just weren't designed with older service panels in mind. You'll probably be eligible for a tax credit and/or manufacturer rebate for going tankless, though. And you might be able to get a better deal from an electrician if you upgrade both your heater and electric service at the same time. I just ...

I think you're going to need an electric service upgrade if you want to use this water heater. Your 100 amp service is already somewhat loaded, as well as the box being physically full. If you call for hot water while the dryer or range is in use (as obvious heavy loads on your panel), you may well trip the main, if you do not upgrade to 200 amp service ...

If the breaker is over 5 years old it is a GFCI breaker and it protects outlets at wet locations whether they are outside or at a sink in the kitchen or bath. Make sure you replace it with the same style (GFCI) Also make sure it is bad to begin with by pressing the test button and if the reset button pops out, it is good, press the reset button to turn the ...

replace like with like. look at the print on it and see what amperage it is rated for and get one with the same rating. the one picture is a double pole breaker that will shut down both leads when either one is overloaded.

Your question is a bit convoluted, but the answer is very simple. The breaker size must match or be lower than the wire amp rating feeding the circuit, and appliances on that circuit should not exceed the max rating of the wire or breaker. In a dedicated circuit for a dryer, for example, the normal size of the circuit would be 30 amps. 30 amps requires a ...

The 50 amp refers to the capacity of the circuit: in particular the wires. The dryer can, and likely does, draw much less, similar to plugging a 60 watt light bulb into a socket rated for a 100 watt bulb. This itself is not a problem. That said 30amp is more typical. If that circuit runs one 30 amp outlet (http://fam-oud.nl/~plugsocket/NorthAm-3hd.html ) ...

One possible investigatory tool is a "toner" set - Fox & Hound or some other brand - While they are are more often used on telecommunications cables, some do claim to work on power wires. User reports vary, possibly due to different toner sets working more successfully than others with power wires. They work by one part applying a small electrical signal ...
