29.11.2011 Removing asbestos sidingAll work on the power supply 3m marine adhesive sealant 5200 is mainly in the connecting cables, installation of switches, sockets and connect the end devices. For cabling, installation of switches, sockets, lamp holder required mechanical and electrical tools: a set of screwdrivers, tweezers, pliers with insulated handles, knife, scissors, pliers with insulated side handles, electric soldering iron, hacksaw, file, mounting a chisel, a hammer , an electric drill, nails, drill bits, masking tape. Fixing the tool must be roadworthy and easy to use, cutting - sharp and properly sharpened. Preparation of materials To carry out the wiring using copper and aluminum cables and wires of different cross sections. Copper wires are in many respects superior to aluminum as the main quality - resistance to bending. Operating temperature wires in the rubber insulation should not exceed 65 ° C, in plastic - 70 ° C. Conductor cross-section is selected on the basis of the maximum value of current, heating insulation, taking into account the mechanical stress on the wire, including the contact terminals of the wiring terminals. As for a few wires, laid in pipes, the allowable value of current in them must be reduced by 10-20%, as the wires will heat up each other. In addition, the channel flush the cooling conditions worse. Cross section at low currents, especially in screw terminals, determine the mechanical strength of the conductor. It should not be less than 2 mm 2 for aluminum conductors and 1 mm2 for copper. If you open the wiring inside the building performed on roller skates, a section of aluminum conductors shall not be less than 2.5 mm2. One disadvantage of aluminum wires is that they are fairly windmill pond aeration difficult to connect. On the surface of the wires and there is a solid refractory oxide film, (they are formed by reaction of aluminum with oxygen), which is a poor conductor. Before connecting the wires to remove the oxide film by stripping. However, it is formed again and prevent adhesion when soldering the solder, and welding forms in the melt unwanted inclusion.Lochinvar boilers Quietside boiler reviews Windmill pond aerator Rift character builder
