The T and P valve is the temperature and pressure valve that is used on hot water tanks as a safety device. The temperature rating is up to 210 degrees F and a water pressure up to 150 psig. (pound force per square inch gauge) before the safety valve trips to relieve water and lower the pressure inside the tank. When the safety valve trips it allows cooler water to enter the tank to cool off the hot water that tripped the valve in the first place. The valve is usually located on the outflow of the tank as the temperature probe has to be located within 6 inches from the top of the tank where the water temperature will be the hottest. The valve is self resetting as soon as the pressure is reduced or the temperature lowers to below the set point of the valve.
Most of the controls on gas water heaters have a one time use overheat sensor that when tripped cannot be reset, the control has to be replaced.
There is no special name for a maximum-minimum thermometer. It generally consists of two scales one will push a slider up as the temperature increases and the other thermometer pushes a slider down as the temperature goes down. You read it by observing the position of the sliders and then reset it so that the sliders return to the current temperature.
You may have to locate the fuse box or circuit breaker box and reset or replace whats needed. Most outlets dont need to be reset unless they have little buttons on them, meaning it is a GFCI outlet - in which case it will have a little button that says reset on it.
As you say you had to reset the circuit breakers, the water heater's heating element may have "died" by shorting to Ground or Earth. This could be the reason why its circuit's breakers tripped to cut off the power. Time to buy a new water heater...? <><><> Typically, you should be able to tell a difference as quick as 15 minutes or so, but it may take well over an hour or two for it to reach "operating temperature". Some electric hot water heaters, you can even hear them as they heat, and you typically can the gas ones. Your biggest variables, assuming you're not using hot water as it heats, is the amount of water that is in the heater, as well as the heating power the heater puts out into the water. Electrics are practically 100% efficient, but gas ones are not even close, but they do operate at higher heater temps and can heat the water faster. <><><> It takes about an hour for a fifty gallon electric water heater to heat up.
Likely one of the two electric elements is going out which creates very high resistance in the circuit and therefore draws very high current (amps) and causes the breaker to trip.
Assuming this means 'what is '.... Light fixtures, motors, heaters, etc all have some form of protection in the event the operating temperature is exceeded to prevent equipment failure or a fire from resulting. Basically, these protective devices are one-time devices like a fuse that need to be replaced, or sometimes are a thermostat type of resetable device, either automatically or manually reset. Recessed light fixtures have automatic reset overtemp devices; electric hot water heaters have manually reset devices for example
Electric fuel pump runs at a pressure of 41-47lbs,the reset is in the tank of the pump itself...goodluck Electric fuel pump runs at a pressure of 41-47lbs,the reset is in the tank of the pump itself...goodluck
There is no reset for a check gauges light. If the light is on, there is a problem either with the temperature oil pressure or voltage.
To reset electric windows on a Peugeot 307, just disconnect the battery for a while. Following the battery disconnect, neither of the electric windows will operate.

drive it. It will reset itself
A Lexus ES 350 tire pressure light will reset on its own. Tire pressure lights will turn off when the tire is at the proper pressure.
Oil pressure lights are not reset. You need to find out why the oil pressure light is on. Normally this means you have low oil pressure.
