Thanks all for the good feedback. A service upgrade to this flush mount meter/main is beyond what the owner cares to spend as it is a major project being it is in a wall that is extremely crowded both structurally and electrically. There is no way to get between the meter and main w/o any modif

Insulated taps are for voltage. L1 is forward, L2 backward, so as to measure total current in both legs with one CT. On Thu, Jul 10, 2014 at 4:39 PM, Corey Shalanski < cshalan...@joule-energy.com> wrote: > Wrenches, > > One of our customers has a utility meter CT cabinet ahead of his main > di

We just went through a similar scenario connecting between a 600A main breaker and five subpanels that were tapped off conductors in a wiring trough. In this case it was a load side interconnection, so the 120% rule applied. We tapped the conductors in the trough and went to our solar fusible disco

Kirpal, I’m curious what the reason is for making the tap on an energized line. Why not have the meter pulled? While insulation piercing taps are designed for “hot work”, there use for that should be limited to tapping conductors that have OCP, and aren’t under load, with generous working space,

In some jurisdictions and for some utilities, pulling the meter is a MAJOR ordeal. Some jurisdictions require a "service change" permit on top of the solar permit just to have the meter pulled. It also requires getting an inspector out there at the perfect time to have it inspected so the the utili

Yes, “I get” that there is inconvenience in coordinating with the utility and inspectors, permitting, and power disruption. In my world that’s just a given part of the process. Of course there are circumstances where disconnecting a utility supply is nearly unavoidable, for instance, certain in

Hi Kirpal, Sounds like you are well informed but I thought I'd throw this in just in case. In Xcel Energy territory in Colorado they specifically prohibit piercing taps for solar installations. I'm not sure why, but you may want to run it by the utility in case there happens to be some solar spe

Dave, I think you are reading the output current for 277V. The spec sheet lists AC max output at 240V as 7700W and 32A. If you take that number at face value, you can still just use a 40A breaker. If you do the math based on their listed output (7700W/240V=32.1A * 1.25 = 40.1A), you might need to
