Yes, see NEC Art 500 and 501
Setting the max motor current too low can cause you grief if, on occasion, the motor needs that current to get things moving. Esp if you have the restart tries set for three. Motor starts, faults,...
It failed at the screw bonding two bars. IIRC, the green screw that would be used to bond the neutral also tied the second bar to the can. Short strap or jumper from neutral bar to green screw tied...
Put the gfci where it is not subject to water and grease.
I have seen this bond fail.
Yes, typical. Should be called normal abuse.
The grounds break off in normal(?) use.
I haven't seen the first RT fittings with the black rubber washer lately. IMO, spit on a die cast set screw connector was better. Maybe they weren't listed.
The Flukes I bought were priced in the same range as this tool and have more than one function. Not a hard decision to make.
The black cord end. How did they even get it inserted into the device? Isn't it polarized despite the missing ground prong?
I agree, put the gfci in. They work.
I agree, but do not low ball these projects. They are time consuming.
Calculated for that point if I understand it correctly.
This comment was for a typical hollow shaft, not the submersible used here.
One mud dauber nest = $800 motor + labor
My question is how does the rf filter affect the operation of the AFCI. Does it filter out the arc signature that it is looking for or just the LED problem?
Thank you .
The runs are just long enough that I will have to buy 500' of cable vs 250' of cable. My help asks me if one motor feed is shielded does the other have to be?. Good question I dont know. Two...
We don't do a lot of houses any more but back when I did buy an extension for my 1/2 inch rt angle that put the chuck out another couple feet from the end. It is angled somewhat so you can get...
IMO, if you have a 4plex, $300 is affordable
Circuit 1 phases AB, circuit 2 phases BC, circuit 3 phases CA. Use two pole breakers, if you want, for each circuit or a three pole if you are happy with one breaker. Nice if the loads are balanced.
Typical aeration fans are not in a hazardous area for grain bins. TEFC is normal.
You will need to get your test equipment out and check for the problems others have listed. Not an AFCI nuisance trip at this stage of the game. Someone screwed up somewhere.
Have the POCO supply 480 and use transformers at buildings as needed if they will not provide underground primary to their pad mount transformers at each building.
Sounds like a deal for us as the end installer because every one of us has the time to do it. Non chargeable time as well. Making sure there are no wiring problems is a must but after that is it...
The Siemens solid state overloads are very good about tripping on phase loss or current imbalance. Zero amps on one phase will do it.
The motor is due to be changed by now. High resistance, low...
