Twofer

It is wired in parallel, such that voltage is unchanged in the twofer, and current is split and divided over two connectors.

It typically relates to a splitter for the UK 15 A power connections commonly used for stage lighting.

[2] Typically for most other power connector types used in theatre, the term (2-way) splitter is used.

As the mains supply is 240 volts these must be connected in series, via an adapter lead or box featuring two sockets.
