Those terms don't sound like US terms. Probably UK etc. Hopefully someone will help.

Thanks for replying Dennis. I'm in New Zealand so might very well be UK-only terms. I have made some progress...
Bus Riser Panel: A Bus Riser Panel is used to connect two sets of three-phase busbars in a panel line-up which are at different levels (top or bottom). Bus Riser Panel's are typically used to connect a Bus Coupler Panel's circuit breaker output to an adjacent panel.

Bus Coupler Panel: A Bus Coupler Panel is typically used in a panel line-up to connect two sets of three-phase busbars using a circuit breaker.

Metering Panel: The Metering Panel incorporates instruments to measure voltage, current, energy, frequency or power factor. Instruments used for measurements include:
-Ammeter
-Voltmeter
-KW meter / kVar meter
-Energy meter
-Frequency meter
-Power factor meter

So only need Incomer Feeder and Direct Incomer now.

Goto local suppky house if you have one and request a catalog. They prolly wont have any medium voltage anything tho. Try semians and allen bradlys websites.

The ABB or Alstom websites are another possibility. They are true international giants in power distribution. I suspect either will have the information in which you seek.
