What are the requirements of air-conditioner safe use of wire

what are freezers for the safe use of wire requires a lot of people think that use of air-conditioner power is not very big, so there is no need to separate a power cord for air-conditioner, actually otherwise. Places such as supermarkets, convenience stores, for example, the general use of air-conditioner is 24 hours, even in the summer, so it is with many home users, in order to the safe running of the air-conditioner, when installing the cooler has specific requirements on the power and ground wire is a must. Let the cooler price to tell everybody what are the requirements. ( 1) Prices for most of the air-conditioner are now a single-phase power supply, working current is larger, the power cord to use dedicated power line, cannot use the flare path, or high current will make the power cord is overheating burned, even cause fire. If you have more than one air-conditioner parallel operation, more should match with enough cross-sectional area of the power cord, at the same time also note on the three-phase load balancing. ( 2) Install the commercial freezer must be reliable grounding. At present, the new building is general public ground wire installed, or the power supply departments set up & the other; Protection by zero & throughout; Line. The user of a building, as long as the three core plug directly into the freezer power supply cord three-core socket. Old buildings typically have ground installation, we must install ground. Live on the first floor of the user, can use 40 mm * 4 mm flat or 50 mm * 50 mm * 4 mm Angle, buried depth of 1 m, with a ground wire is introduced into indoor, assembling three-core socket. Such as high-level, use tap water tube, as safety grounding protection. From the water pipe on the ground, & # 39; To use wire clamp and pipe's prison, to ensure good conductivity. And drain pipe, heating pipe, and the earth wire must not be allowed to do with gas pipe. Has done this, so in terms of the safety of the use of air-conditioner, as much a layer of security, so everyone is in accordance with the above experience to perform better.
