A test probe has a probe portion, a current source lead attachment portion and a voltage sense lead attachment portion. The test probe includes two conductive halves secured together with an electrically insulating material disposed between the halves electrically insulating them from each other. Each half has an “L” shape including a probe portion and a test lead attachment portion extending perpendicularly outwardly from the probe portion, and provides the test probe with an overall “T” shape. The conductive halves can be made of copper-beryllium. Methods of providing and using the test probe can include uncoupling a male coupling member of a power cable connector of a loadbreak bushing assembly from a female coupling member of the loadbreak bushing and inserting the rod-shaped probe portion into the female coupling member.
