Iíve seen a nice dishwarmer for sale in Silverprint and am thinking of getting one. My darkíshedí can get quite cold and keeping lith developer up to temp is a real pain.

Iíve a (probably silly) question to ask about the use of a dishwarmer. As its an electrical device, working close to water/liquid, is there a danger of an electric shock from it? Should it be used with a RCB?
