My home has been decorated, and now the home for hot water, regular maintenance, and then want to install an electric water heater, the main Wei has a shower.One problem: can use hot and cold water outlet pipe connected to the shower where joint to install electric water heater?Question two: if so, then the hot water can flow to the guardian, the kitchen and wash the pool?Question three: if you buy instant heating, can the toilet wire be able to withstand it?
Protection requirements.The total meter load of the household can not exceed the standard. It is better to have an air protection switch, at least a fuse protector - such as a safety tube (wire) and a nominal value of a safety tube (wire), shall not exceed the limit value. Water storage type electric water heater shall be provided with a separate power supply line, stop and other high-power appliances (such as water heater, heater, electric heater) share a power line (note the connection from the meter rather than from the socket, the wall cannot connect from the middle), a separate set of leakage, overload and over-current protection device, the protection of the current value of 2 times the level shall not be greater than the rated current of the single electric appliance.
Home power standard.In accordance with national standards, the power supply of household electric equipment shall be single-phase, three wire, 50 Hz, 220 volts alternating current. The three lines of the power supply - the fire line, the zero line and the ground wire are correctly connected and in accordance with the external mark. The grounding is good, the insulation protection is in good condition, and the wire diameter thickness meets the capacity load requirement. In the national power quality, the allowable voltage of the supply voltage is -10% to 7%, which is between 198 volts and 235 volts according to the standard voltage of 220 volts. For electric water heater products, the deviation is extended from -15% to 10%, or between 187 volts and 242 volts. In areas where the electricity load is relatively concentrated, the expansion should be done appropriately
