Reuse of interface blocks.

[amit.kalhapure@gmail.com]

Hello,
There is block with 2 proxy ports for AC and DC electrical power.
Is it ok to use single Electrical interface block having value property of AC & DC and assign it to 2 proxy ports?
OR
Is it advisable to use 2 separate interface blocks for AC and DC and assign it to 2 proxy ports of AC & DC respectively?

Thanks in Advance.
Amit.
