Re: [RE-wrenches] useful info on wire color coding

Interesting, there isn't a code requirement to color code for phase rotation, but it is common practice for black, red, blue to correspond to clockwise rotation. Also notice on the DC table, that John Wiles recommends (but isn't NEC required) color coding for a positive grounded system: white f

Re: [RE-wrenches] phase rotation wiring

I should know this, when you face the motor looking at the shaft it will turn CW when it is wired ABC or Black Red Blue, for 120/208 or 240  3phase BUT BUT you had best not trust the color code, the code no longer requires colors, and when installing motors we always test.  There are testers tha

[RE-wrenches] phase rotation wiring

There are two situations one can find when working on three-phase AC systems: a clockwise or counterclock phase rotation. Is it correct to assume that a CW rotation would be color-coded (for 120/208V) from left to right black-red-blue while CCW rotation would be, say, red-black-blue? Or whe

Re: [RE-wrenches] aluminum wire failure photos

We don't often get to take picture, as the point of failure is hard to find, and the entire underground line is just abandoned and a new cable is installed. Most failures I've seen (not actually seen) were on improperly installed runs, done by DIYers. On the other hand, the majority of undergroun

Re: [RE-wrenches] Voltage discrepancy

Bob you know the architecture of the MX60 is it a design problem or is it a component problem, I have not noticed this problem in older MX60s but I was not looking for it either. I have been able to adjust the meter and I typically would not check it again. I use my meter and adjust the MX60 t

[RE-wrenches] aluminum wire failure photos

Does anyone have any photos of aluminum wire that has failed? Failures from nicked insulation and such would help. I have a debate going with a customer who does not believe that it could cause a failure. If you have any digital pics please send them to my address, reelli...@gmail.com instead

Re: [RE-wrenches] Voltage discrepancy

Not sure if it's already been brought up or not.. but you might want to recheck all connections.. just to eliminate that issue.. dbDan BrownFoxfire Energy Corp.Renewable Energy Systems(802)-483-2564www.Foxfire-Energy.comNABCEP #092907-44 Original Message Subject: Re: [RE-wrenche
