Simon Chaddock Posted December 14, 2010 Share Posted December 14, 2010 My suggestion is find a similar looking one on e bay. They usually give pretty accurate physical dimensions (L,W,H). If it looks exactly the same and is the exactly the same size it probably has the same current capacity otherwise be safe and assume it is 20A..
