In most cases, water is entering through the the rubber compression gasket at the top of the meter where the service wire enters the meter. Have power company turn
off power and have electrician replace compression gasket and add Ge silicone around top of compression nut. Also add silicone where the service wire exits the meter at
the bottom of meter around wires to stop water entering the sheathing of the service
wire. Inspect door gasket and dome lock to stop wind driven rain and snow.
10/3 wire with 30 amp double pole breaker from panel box to water heater.
Sounds like it is a 220-240 Volt hot water heater. The black and red are connected to the 220 volts supply and the white is connected to Neutral. At the breaker panel red and black connect to the 2-pole 220 volt breaker and white goes to the neutral bus bar.
The best way to determine which circuit breaker is for the water heater is with a voltage meter, It is suppose to be only one circuit breaker, but in a faulty application it could be two breakers
A shunt trip breaker is installed like any other molded case breaker. The only difference is that it has an internal tripping coil that is usually connected to a C.T. The breaker is usually mounted in a MCC cabinet The top of the breaker is bolted to the MCC bus bars and the bottom of the breaker is connected to the load. The load conductors pass through the C.T.'s which induces a current into the circuit to trip the tripping coil in the breaker.
What governs the type of breaker is the voltage and wattage of the heater elements. If the tank is 120V then you would only use one breaker. The size of the breaker you use will depend on the watts of the element. Watts = amps x volts, Amps = Watts/ volts. Once you establish the amperage then size the wire and the breaker to fit. If the tank is 240V the same rules apply only you would use a 2 pole breaker. IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS. If you do this work yourself, always turn off the power at the breaker box/fuse panel BEFORE you attempt to do any work AND always use a meter or voltage indicatorto insure the circuit is, in fact, de-energized.
There is no way of telling from here. It will be a double breaker, most boxes will have 3 doubles. One for the stove, one for the AC and one for the water heater. Process of elimination should tell you which is for the heater.

Generally a bad idea. Esp if the area is ever unheated (basements). Water in the pipes can freeze, burst, and become a serious safety hazard above electricity. (The main line coming in from the pole is not protected by a curcuit breaker. So if the main lugs are getting water on them there is no breaker to trip and automatically turn of the electricity.)
Your water system is not grounded. Turn the main breaker in your distribution panel to off and ground the water system. If a "hot" wire has come into contact with the plumbing, when you turn the electrical panel main breaker back on a breaker will trip. This will give you the circuit that is at fault and a place to start looking for the short circuit.
Assuming you are referring to a 240 volt residential hot water heater you will need to install 10/2 NM cable (Romex) with ground from the service panel to the water heater wired to a 30 amp circuit breaker in the service panel. If you cannot see the water heater from the service panel you will need to install a service disconnect at the water heater.
You can pull the front panel off the Hot Water tank and there is a red reset button on the electrical that controls the power to the elements. Or, try resetting the breaker on the electrical panel serving the tank.
A vacuum breaker should not leak at all. The purpose of the vacuum breaker is to control the atmospheric pressure inside a geyser. If it is leaking, it means the rubber seal inside has either broken or has perished and needs to be replaced.

it is used in a harbor where ships dock. breakers lower wave intensity so safe docking can be achieved. a breaker is no more than a big wall that runs underwater and above water.
Yes. Water can damage the breaker and prevent it from working, or it may continue to carry current after the breaker trips.
In the United States, if the wire is #8 copper or larger (smaller number) it will work fine on a 40 amp breaker. If the wire is #10 copper, there is something wrong with the breaker if it does not fit. Pull the breaker out of the panel and look into where the wire terminates to see why the #10 wire won't fit.
