If you extend a existing 3 wire dryer/range receptacle,wouldnt you need to bring it up to compliance w/ current code(s) since 250.140 applies to EXISTING installations and if one extends it IMO it would no longer be existing....
Yes it should be brought up to code, too ,many guys afraid to tell the homeowner, it should be code compliant, not wanting to open the walls or spend the money, is not a valid reason, to ignore the code
Good point Les,
You guys are lucky that you don't have "Self-Certification" over there, you can marry yourself to all sorts of problems if you either don't inform the Home-owner or blindly install something that would never pass an Inspection.
With Self-Certification, you are audited every March and are asked to send in a certain percentage of your Certificates of Compliance to the Registration Board here, an Independant Inspector will look at your CoC's and will then look at the work done.
There have been Electricians AND Inspectors de-registered with the audit system, here, it keeps everyone honest, to a degree.
Just my $0.02 worth.
