"Yossi had lied right to my face, when leading me to believe and trust that his company would perform the best work according to present-day code and safety standards, yet knowing that the electrical work would not be performed by a qualified, licensed bonded electrician! ...Then it dawned upon me, when Yossi came to my home for us to meet, for the very first time, he was afraid to even crawl into the attic to inspect the job for himself, personally and first hand. As such, he wore a surgeon’s mask and just momentarily peeked into the attic. When I inquired why, he told me he was allergic to the insulation. When an owner of an attic insulation installation business is allergic to his own product - well, I should have been forewarned right then and there of the possible potential future dangers and pitfalls!! …Now, I'm faced with the additional expenses of having a licensed professional electrician rewire, that entire attic exhaust fan, in accordance with national NEC codes, and city building safety standards. ...On a side note: not even related to Y&S's shoddy, shameful and illegal electrical work, they also missed installing any insulation to an entire section directly adjacent to my attic furnace - thereby, not even completing nor fulfilling their insulation installation responsibilities and contractual obligations. ...In all fairness and good conscience, I could not/would not recommend nor refer anyone in the interest of trust, confidence, safety and sound building ethics, to ever hire Y&S Home Builders for any insulation or attic work. NEC (National Electrical Code) Article 370 Section 17, Boxes, Conduit Bodies, and Fittings General Installation: “This article addresses installation requirements for fittings used to join raceways, and to connect raceways and cables to boxes and conduit bodies. Connectors, couplings, and conduit hubs are examples of fittings discussed. … Section 370-17 states that conductors entering boxes, conduit bodies, or fittings must be protected from abrasion. Compliance with this requirement prevents sharp edges from rubbing, scraping, or cutting into a conductor’s insulation. Without the proper protection, by fittings or other means, conductors entering knock-out openings of metal boxes (or enclosures) are susceptible to damage. Scrapped or cut conductor insulation creates a safety hazard by exposing live conductors. Section 370-17(a) stipulates that openings through which conductors pass must be adequately closed. Compliance with this regulation is usually accomplished by simply tightening the fitting that secures the conductor to the box. Improper selection or use of a fitting may constitute a violation of this requirement. … Safety is every electrical inspectors goal, and effective electrical inspections will help to minimize, or may eliminate conditions that lead to fire and electric shock hazards. … Article 100 in the National Electrical Code defines a Qualified Person as One familiar with the construction and operation of the equipment and the hazards involved. …Electrical Inspectors often encounter poor or shoddy installations performed by persons who are not qualified or even familiar with the electrical system and its operation. In many cases, unqualified individuals have installed or performed inspections of electrical systems with little or no training, or knowledge of the rules of the National Electrical Code!”"
