In '99, it became a requirement to paint or permanently reidentify white conductors of multiconductor cables that are being used on switch loops as hots. I think the "permanent" part of this excludes the use of tape. Has anybody got a good way to do this? I've been using a "paint pen" (like an enamel felt marker), and the wire's all sticky unless it's left for days and days.
If your area won't accept tape, how about a short length of PVC sleeving?
We often use red sleeves over blacks (normally neutral) here to identify switch loops. It's permanent in the sense that it won't come off unless you cut it or disconnect the wire from the switch terminal.
Thanks! The heat shrink sounds like it would be a very good way for us to go. The 3 wire cable (BX?) would be cost prohibitive for us. We do lots of offices, and unless the jobs require it (some occupancy sensors need the neut), the added $ would add up to quite a sizeable sum.(I already got shot down suggesting this)
