A-4-1.1 Electrical installation for dwellings should be inspected and approved by an authority having jurisdic tion. such as an electrical inspector. Here are some thin« to check to assure that electrical installations are comjdeted properly. (a) Make certain that fuses or circuit breakers of the correct capacity arc used for the electrical circuits. If the fuse or circuit breaker is of the incorrect capacity, then electrical overload of the circuit may cause overheating of the wiring and breakdown of the insulation, with lire resulting. (b) All wiring should be fastened securely to recep tacles and fixtures. Frayed or loosely connected wiring can result in arcing and shock hazards. (c) Fuse and circuit breaker panelboards should be located in a dry' area so that the danger from moisture will be minirniztd. All metal enclosures and ot.her noncunent-carrying metal parts should be cffectivcK grounded. ... (d) Modern approved cables with a grounding wire or metallic enclosure properly grounded during installation should be used. Only grounding-type outlets should be installed on such circuiu. Figure A-t-l.lU) Oon ‘1 do ihiil .Make «urc there are enoufo electrical oudeii to tenre all appliancea without overloading. (c) Since a great deal of the older-type electrical cir cuits without a grounding wire arc still in use. particular flPWi attention must be given to oiner meihod.s of properly grounding modern electrical appliances on such circuits, such as by clamping a grounding wice to a meial ground ed cold water pipe.(f) Service drops between the srrxicc pole and the weather-head are a source of fire ignition and installations must be made carefully to minimize the danger. All splices and connections in the service drop wire between the service pole (transformer) and weather-head mu.st be made with proper connectors. Generally, this type of in stallation is made by power utility companies. (g) A drop cord or lamp holder is built to carry safely only the current demanded by a lamp bulb and will overheat when used for appliances drawing more rurrent. (h) Discard appliances that do not bear the label of a recognized testing laboratory. The label or listing should be for the entire appliance or other assembly and not just for the cord alone. A-4-1.4 Outdoor electrical receptacles are protected against weather by weatherproof covers. Always be careful to have dry hands and to be standing in a dry area when inserting or removing a connection from a live elec trical circuit. A-4-I.5 Electrical circuits, tools and appliances are grounded to minimize shock hazard. This is panicularly important when persons are using power tools outdoors and may be standing on wet grass, soil, or other moist surface. Make certain that the tool or appliance is grounded properly or double insulated. (a) Never allow curtains, draperies and similar flam mable or combustible fabrics, plastics, or paper products close to electric lamp bulbs. (b) Restrict extension cords to their proper use: such cords should not be run through walls, windows or doors 01 undc»- carpets or be used for permanent wiring. (ci Replace frayed, worn or spliced or taped cords im mediately. Repairing of cords may result in additional hazards. (d) Discon 'ect all appliances such as toasters, portable space heaters, coffee pots, or hair dryers and pressing irons when not in use. (c) Extensions to permanent wiring often create serious electrical fire hazards because of improper joints and splices and the use of lamp cord as ericnsion material. # (f) When certain parts of electrical equipment or ap pliances are found to be wearing out, or about to break down, examine the entire appliance carefully for other possible faults. A-4-3.1 In areas where lightning occurs frequently, in stall lightning arresters for the main electrical service. Dwellings and cottages exposed in open areas where thunderstorm activity is frequent should be protected by a properly installed and maintained lightnmg »'od system in accordance with NFPA 78, Lightning Protection Code, Section 21.
