I don't completely agree. Things that are VE'd out don't' need repairs or maintenance. It doesn't exist.
EMT fittings, MC cable, aluminum feeder wire doesn't wear out. Breakers with a lower AIC rating don't break down. Aluminum bussing in switchboards last as long as copper.
The switchboards/panels and terminations should be serviced and scanned and re-torqued periodically on expensive gear as VE'd gear, does it not?
I think lighting is the main product that needs more continual maintenance re-lamping/ballasts and cleaning. Does a cheaper fixture need to be serviced more than an expensive one? They contain the same lamps and ballasts as the expensive one's in most cases (I'm talking commercial grade stuff here, not resi-grade)
Someone explain how VE'd electrical results in more repairs and maintenance.
I think crappy installs are the biggest cause.
Some items in some places will not wear out. Install EMT in an area that gets physical abuse at times and it very well need repair or replacement at some point where RMC or IMC may stand up to the abuse.
I have a building about 10 years old, the owners wanted me to check what is wrong with some exterior lighting. Several recessed 70 watt metal halide fixtures - all have bad ballasts. About half of the entire exterior lights are out. If I replace them guess what? The other half will probably be failing soon. These were typical fixtures I've seen specified a lot, or at least something very similar. They are expensive to start with and replacement ballasts are not cheap either. I would rather see some CFL fixtures myself. Maybe even something with LED - but remember it is about 10 years old, they may just specify some of that today. The CFL cost less both to install and maintain, and use less energy.
