An arc-resistant electrical terminal includes a mount portion and a wire receiving portion formed of an electrically conductive material. The wire receiving portion is configured to be crimped onto a wire. The mount portion includes a solid tongue having opposing face surfaces. An aperture is formed between the opposing face surfaces for connecting the terminal to a connection point. A layer of insulation material is formed on at least a portion of the tongue for preventing arcing at a connection point. A raised boss is formed to surround the aperture on at least one of the opposing face surfaces of the tongue, the raised boss providing an electrically conductive surface of the terminal free from the layer of insulation material for connection to a connection point.
