What is the expressed purpose of the NEC? Or, for that matter, any model code?
"The practical safeguarding ....."
I submit that every time any other motive is applied to the NEC, it loses some legitimacy- no matter how well-intentioned the new influence is.
Regarding changes in the NEC over the years ... I simply cannot accept that the 1963 new house I was raised in was a deathtrap. Yet, the electrial would need extensive redesign to meet today's code. I have a problem with that.
Still, I recognize that the original 1963 wiring design is not adequate to today's needs. Indeed, I recall our adding quite a few receptacles to the kitchen counter, just to illustrate the point. Yet, again, we have here the distinction to make between 'minimum' and 'ideal.'
The point was probably best made when the NEC (2005? 2008?) decided to require a phone jack be installed. A phone jack- at a time when many folks are doing away with hard-wired phones completely. I just have to wonder how we all managed to figure out we needed phone jacks for the 100+ years before the NEC discovered this need. Just as amazing is that we actually had things that the NEC did not require!
Likewise, the phone guys had all manner of gizmos for landing their ground wires for decades before the NEC discovered a need for an 'intersystem grounding terminantion.' An amazing transformation then took place: a $6 ground bar suddenly became a $50 "IGT". What's going on?
Set aside the evil manufacturers for a moment. We have all manner of folks working overtime to insert their 'expertise' into other folks' business- backed by the force of government. It sure is easy to make decisions for other folks.
The result is that the less competent, less conscientious, less regulated guy starts to gain advantage. Why build expensive new apartments, when you can stumble along with the old shack ..... it's not like the tenants have much choice. After all, we've let the "system" ensure that competing landlords are faced with an all-or-nothing situation regarding upgrades.
We also make it easier for the 'gray market' contractor. The guy who does 'side work,' or simply operates below the radar.
Then along comes some college boy who asserts that these 'outlaw' activities demand greater governmental intrusion .... failing to recognize that governemntal intrusion is what created the situation.
So ... what can we do?
Well, part of the solution is to limit ourselves to accepting the customers' goal and giving a simple price. Do NOT trouble the customer with the details of what you need to do - or he'll be questioning your every move, every choice. Don't tempt him.
Likewise, even the first call the customer makes needs to stress that you are the REAL THING, a real contractor, and not someone sitting in a bar waiting for the cell phone to ring.
Next, accent the positive: YES, I can do it. I can do it FASTER. I can do it NOW. I'm PROFESSIONAL. I will do all the ADDITIONAL stuff ... repair my holes, clean up my mess, work around your schedule, etc. Stress all the 'extras' the trunk-slammer won't provide.
SELL the job. Why do you think folks like Service Magic place so much emphasis on truck artwork and uniforms? It's because they see the value in looking PROFESSIONAL.
Finally ... and here's the hard part ... you want to make the customer want YOU. You need the customer to believe that you don't work for just anybody, that only the BEST customers get your services. Everyone wants to be among the 'chosen few.'
