Re: Christmas Lighting
I?m honestly surprised I?m on the ?other? side on this one. I?m one of the most permissive design engineers I know. However, I?m more concerned with actual safety than Code compliance. I fought many Code proposals over the years to make things ?safer? when I believed the current status was ?safe enough.? I?ve even had a few proposals accepted that relaxed requirements a bit. (I?m still battling CMP1 over some poor implications of 110.9. My support among ?Users? is growing and I?ll win this one if don?t die first.

)
You draw a line between ?safe? and ?unsafe.? Where you are choosing between ?safe? and ?safer? it?s reasonable to consider cost, convenience, esthetics, performance, personal preference, as well.
I believe a Professionally Engineered design is:
1.) Safe to an unsuspecting public
2.) Safe to trained workers
3.) Does the job intended consistent with 1 and 2
4.) Is cost effective consistent with the 1 through 3.
(#3 is usually where client convenience, esthetics, performance, personal preference etc. comes in.)
I still haven?t said I believe a lack of GFCI is unsafe or not in this situation. I?ve said if someone believes it is unsafe they can?t leave it that way, ?compliant? or not; and I?ve offered a substantial basis to support the position.
While I may not be able to sue a mechanic for not upgrading the brakes on a Mustang, 68 Firebird, or a 50 GMC pickup, in most states I can force the owner to install seat belts even in automobiles that didn?t originally require them at time of manufacture.
