Ralco® Plug

Top Definition

The Ralco Style plug dates to the earliest times of switchboard design when the circuits were switched with patch cords similar to the old phone switchboards. Made of wood with bronze contacts, they handled heavier ampacity (30a) loads for portable devices. Currently offered as replacement parts under the Amphenol / Pyle-National line which address the arcing issues that arise from higher amperage direct make/break through fully enclosed contact chambers. While they are not used today in new installations, the installed base is sufficiently large to justify Amphenol's continued support of this product. (See OLDtimer story)
