thanks Alehman,but I thought since many manufacturer installation documents are referring to LOTO procedures while working on electrical parts I thought may be there is something to it.
I would recommend you take a reading at the worst time and add to it %25 as code recommends when you want to add a new load to an existing service. Use software to see if generator will take it. That %25 will give you latitute for during emergency loads will be shifted to emergency, (those that...
When you use transformer backwards you need to make sure that your tap settings are at normal otherwise your core losses will be high and transformer will run hot based on tap settings.
I do not think you can easly coordinate fuse with CB for few reasons.
Maximum let thru does not mean much for the breaker because breaker may try to open before the fuse clears. Critical is the energy load until CB opens. Typically on high available short circuits curve is very steep causing...
When you have short than your voltage is down to %15 of original, so your voltage drop is around %85.
Furthermore generator can sustain probably no more than 10 seconds which after that they are fried.
It affects the life of the generator rule of thumb is 100 times short you are out, generator...
Somebody can help me.
What is the working clerance for ceiling mounted mechanical equipment that has electrical controls mounted on them.
Do I need 3ft clearance, if yes why. How does it help when you are on top of a ladder. I know 110.26 do not differentiate floor mounted or ceiling mounted. Is...
