Out West, many electric utilities adopt EUSERC service-entrance standards, where generally the utilities provide only components that they install inside metering compartments, but not sockets. [www.euserc.com—looks like ~6 pages of member organizations] In those areas, instead of utility-furnished sockets that are stanchion-mounted by contractors and ‘Grecian urn’ CTs in a padmount transformer, bussed metering bar-CT/PT/meter/test-switch [and cable-pull] sections are provided meeting utility specs.

These days, PDF files on web sites simplify the process.
