Help out a dumb engineer...
We're planning a line side tap into existing gear for a commercial PV installation. The PV aggregates into a 1200A switchboard which will then go in as a line side tap into the existing main switchboard (2000A bus, 1600A main). POCO is OK with the arrangement as long as we don't break their seals and maintain the UL listing of the gear. So my questions are:
- What does that line side tap actually look like? Seems like an awful lot of tapping going on a pretty small area.
- The switchboard is a top mount meter with a bottom mount main. Is it at all realistic to be able to come in from the top without breaking any POCO seals?
- Is there any chance of getting the manufacturer to sign a document that the UL listing will not be compromised for 25 year old gear?
- Is there a better way to go about this without breaking the bank?
