It's called ledge mostly because it sticks out like ledges all over the place. I had to have half of my home's foundation site blasted to fit the foundation.
I found several places where there is a ground rod in place and then tied to the building's main columns. I should be okay tying to...
Ledge is what they call bedrock in the Northeast. Very few places can go 8' deep around here without hitting ledge/bedrock.

Hello,
I am installing a small (60A) sub panel in our work shop. The plant is powered by an ungrounded Delta system. The 480VAC feeds a set of transformers and steps down to 240 3 phase. This feeds a bus that distributes to various things. I want to add a small 12 circuit panel of 208 VAC...
We have a machine that the OEM installed an eWon module (https://ewon.biz/product-gallery). They have a slew of products for communicating with machines and between machines. I don't have a lot of experience with them. The one in our place needs access to the wi-fi, though. Good luck...
Good afternoon,
I installed the Yaskawa A1000. Upon power up I noticed that there was PG (pulse generator) fault. I thought that was odd since we don't have any encoder on this. I hooked up Yaksawa Drive Wizard and started going through the parameters to find out why I had this error. The...
Thanks guys.
It's been running for the last 24 hours with the wires directly from the drive to the blower.
I did check the contactor while energized. I've been bitten by the "push it in with a screwdriver" test too many times.
This one really has me befuddled. Although I am intrigued...
I measured less than a volt across the contacts on the contactor. That leads me to believe there is no voltage loss across the contacts themselves. Electricity is fun until it's not.
Thanks for the reply.
We did all that. In fact, more than one of us did all that.
The drive is now working normally. I truly suspect the VSD is bad. It's fairly old and has been used in an area where the ambient temperature is frequently over 100 deg F especially in the Summer. Right...
Good morning to all!
I really need some help. We have a blower run by a 15hp motor. It's a Baldor SuperE model. It's rated at 17.5A and 3400 rpm. Yesterday the inverter (TB Woods 4000 series WFCht) stopped working. This was after getting faults of a phase imbalance. (I was not there...
