A local panel shop is constructing a small water tower control panel for me that's about 80% complete. For the most part it's a beautiful job, except for one thing - the wire markers are standard Brady translucent vinyl tape instead of the heat-shrink sleeve markers that were specified and bid on. Oops.
Yes, the panel shop will replace all the wire markers with sleeves for free if pressed, but I don't want to make them re-wire the whole panel using the sleeves unless there's a real benefit to doing so.
The heat-shrink sleeve part of the specification was a result of problems with old vinyl tape markers falling off years ago. The panel shop supervisor tells me that the adhesives and materials are now much better and will not fall off, and that the heat-shrink sleeves I had specified really don't perform any better unless the marking is 'burned' in, rather than printed on (which can smear)
Is the panel shop supervisor showing me the light, or just trying to avoid having to re-wire the panel?
Does someone have guidlines for best wire marking methods for different environments, font and label sizes, regulations, and such?
Best regards,
Joe Manns
