In one aspect, a conversion terminal device for electrically coupling dissimilar metal components is provided. The device includes a body having a first layer coupled to a second layer. The first layer is formed from a first metal and the second layer is formed from a second metal different from the first metal. The body includes a first connector portion and a second connector portion. The first connector portion is configured to couple to a first electrical component made of the first metal, and the second connector portion is configured to couple to a second electrical component made of the second metal to facilitate electrically coupling the first electrical component and the second electrical component.
