Stop worrying and start living by learning the “Basic Electrical Wiring”

Basic Electrical WiringWe can’t think of life without electricity, specifically those city dwellers whose life resonates with the every spark of it. So goes with its usage that calls for one’s basics in electrical wiring for the good. Just imagine, it’s a hot and humid summer night and the power went off at your home by midnight for the fuse wire. Can’t call a mechanic at unearthly hours – open to two options only, either do it on your own or suffer till next morning for a mechanic to report. Additionally, be prepared for late to office etc. A trivial example, that connotes a lot. Basic electrical wiring knowledge therefore is a hot pursuit in our daily life and it means –

• A popular programming language which is relatively easy to learn and determines the depth of one’s knowledge while working near electrical circuit.

• Confined to the arena of home wiring only.

An individual can wire his / her own house for family dwelling that must conform to the National Electrical Code (NEC) of 2011. NEC gets revised in every three year period and hence, one must review it before getting into any project like this. Caveat: NEC can’t be construed as a fit for a practical, hand-on experience.

Ambit of NEC:

1. All splices must be placed under a covered junction box. Junction boxes must have access; not covered by drywalls or wall coverings.

2. No bonding on double insulated circulating motor pump and hydromassage bath bulb.

3. For wiring connections apply wire nuts or other approved means, don’t rely alone on soldering or tape.

4. All boxes meant for splices, receptacles, switches or lighting fixtures must be spacious enough to accommodate wiring and electrical fixtures.

5. Metal boxes, covers and plaster rings must be grounded on use.

6. All unused openings in boxes, panels etc. are to be sealed with approved closures.

7. All switches including dimmer switches too are to be grounded.

8. Color coding or tape marking must be done as a mark of hot conductor on white insulated conductor in a cable, if it is used as a part of the switch loop for single pole, three way or four way switches.

9. Each wire / conductor in a box must be a minimum of 3 inches in length from its opening.

10. All grounding conductors must be tied up and secured while in a box.

11. The receptacle used for heavy duty home appliances like wall-mounted ovens, counter-mounted cooking units, cloth dryers etc. must be a three-pole, four-wire receptacle and on a four-wire cord. Make sure that the bonding strap is not connected between the neutral terminal and the appliance frame in an appliance junction box.

12. Wooden members like studs or floor joists must be kept at least 1.25 inches away from Romex cable.

13. Romex is required to be securedly placed or stapled at a regular interval of 4.25 feet or 12 inches of every panel.

14. Install approved nail plates or make holes 1.25 inches deep from the wood members.

15. Direct burial wire must be 24 inches deep in general followed by 18 inches deep electrical conduit from the top of the conduit. All wiring passing through driveway or sidewalk must be at 18 inches deep.

16. List the insulated conductors and cables in an enclosure while using it in a wet location.

17. Smoke detectors must be installed in each sleeping room and at a centrally located point on in the corridor.

18. Nothing less than a 100 ampere and three-wire electrical service is permitted for a single family dwelling.

19. Call for an inspection post electrical works.
