Tips for good wiring
To carry out a precise wiring project, it is necessary to take into account everything from the installation of the pipeline to the connection of the electrical accessories.
new constructions and remodeling, correctly wiring the electrical system will allow us to guarantee our work. This time we will talk about the best way to do it; leaving for another moment the calculation of the necessary circuits for a residential electrical system.
Tip 1. If it is a new construction built of solid partition and cement slab with rod laying, the installation of the pipeline in the slab should be prepared according to what has been published in other sections of the magazine; that is, selecting the correct pipeline and taking all the fastening recommendations for it.
Tip 2. It is important to consider the number of outlets for lighting, so it is necessary to have a plan or sketch and compare the physical installation against what was previously projected on paper. If you do not have this comparison, the location of the outlet boxes may be misaligned, or be insufficient for the number of luminaires to be installed.
Tip 3. It is convenient to select the pipe well, taking into account the occupation of the conductors within it to avoid overheating and allow the installation of more conductors for future extensions.
Tip 4. The boxes for switches and contacts must be located at the height indicated by the customer or in compliance with the need to be covered. For example, to power a screen installed on a stand.
Tip 5. The conduits for communication systems and coaxial cable circuits must be separated from those of the electrical system.
Tip 6. The contacts for general use can be located at a height of 0.4 and 0.5 m, these are to connect table lamps, entertainment center appliances, among others. In kitchen circuits they are to connect refrigerators, stoves, garbage disposals, etc.
Tip 7. When the appliances are used on the kitchen counters, the contacts should be located 0.4 m above this cover.
Tip 8. It is recommended to place the outlet for switches 1.2 m above the finished floor level, as it is enough for a child or a person in a wheelchair to manipulate it.
Tip 9. When you have ensured that the pipe routes are clean, trimmed flush with the outlet box, and roughened to prevent damage to the conductor jacket, proceed to the conductor installation. First, we recommend that you measure the paths of the cable runs to form cable bundles and install them in one step, thereby reducing time and effort.
Tip 10. If you use a POLIFLEX nylon guide , we remind you that it has two ends: the finder and it pulls cables, so you must attach the first cable -the one with the largest diameter- to the cable-strip tip and the others in a staggered manner. the first driver. All of the above firmly fastened with insulating tape; If necessary, apply a little lubricant for wiring and totally avoid the use of fluids that are not suitable for electrical wiring. Identify each conductor to find out which circuit it corresponds to.
Tip 11. When all the cables have been installed, make the drops to the switch outputs and contacts.
Tip 12. The connection of the down conductors to the branch circuit conductors is made by means of a T-type joint to avoid sectioning the conductor. If it is not possible to make this splice due to space reasons and it is necessary to section the conductor, you can use the rat tail splice. Once the splices have been made, tape each one correctly so that the insulation is equivalent to the conductor lining or use the threaded protectors or caps that are included in the kit inside the POLIFLEX roll.
Tip 13. In the outlet boxes the precise length to be left is 0.15 m; takes as a reference the amount of stripping that manufacturers mark on electrical accessories. Read the manuals before starting the connection because some have different fixing means than the conventional ones; for example, push-in terminals do not require tightening of a screw, or the conductor is clamped between two metal sheets compressed by a screw.
Tip 14. It is important to verify the installation material, that is, if the conductor can be copper or aluminum, or only one of them.
Tip 15. Before powering up the system, perform an insulation test for each contact, luminaire and continuity output for the switches in conjunction with the lamp outputs they control, this will give you the certainty that the wiring is correctly done without short circuits and is therefore safe for those who will use it.
