I was talking to a friend who recently wired his own house. He said that the code stated that there was a requirement to have red loomex for heating circuits, blue for bedrooms, yellow for lights etc. He lives in a different city.... I recently wired my brothers new house with your basic white loomex and had no problem with the inspector. I checked the BC electrical code/bulletins/directives and found nothing on this. Does anybody have any comments on this? Maybe there are local rules with certain inspectors?

AFAIK there is no code issues the colouring is just there to provide a means to identify conductor size, voltage and circuit type in a round about way for when the inspector comes.. I have heard of houses where the general lighting and receptacles were done in blue and the AFCI's in white with no problem BUT I almost got 'dinged once for using a piece of 12/2 yellow ( black and white conductors) for a 240V electric heater instead of the 12/2 red ( black and red conductor), even though I identified the white wire as a hot.

No size limitation for rendering the identified conductor unidentifiable when using loomex or bx.

That is correct... take a look at 4-034(1).

Mr_Electrician:
The reason I was given is " Someone may mistake it for a 120V circuit and tap into it".. A bit far fetched if you ask me, and I have seen tons of 240V installs that have been done with regular 2 conductor ( black and white ) romex with no problems... I wonder what would have been said if I happened to have used AC-90, how that would have played out.
Speaking of AC-90, I have worked with the "iso ground" AC-90 before. I was told it was because of too many people connecting the red to a breaker and not to ground, making for a dangerous situation..
I am not sure and I will check, but I *think* that regular 3-conductor AC-90 may be used as long as the red conductor is sleeved with green heat-shrink tubing and NOT taped, and done in every box the cable is spliced or terminated at..

There was an ESA bulletin on this. Ever since iso wire became available, we can longer use regular 3 wire BX as iso ground on new installations. Some inspectors may close an eye, but in the eyes of the code, it is a violation.

Rule 24-104, in the "Patient Care" section, mandates the use of a insulated bonding conductor, unless insulated by way of a non conductive raceway or by the construction of the cable containg the conductor.
Rule 4-036(1) mandates that a insulated grounding or bonding conductor be green or green with a yellow stripe.
Using any other color as a bonding or grounding conductor, is permitted only if the conductor is a #2 or larger and if it is permanetly re-identified as required by 4-036(1b) and "no", tape is not adequate in my books.
