Abstract: A surge protector is provided for a multi-phase watthour meter. The surge protector allows all three phases to be protected using a single resistive block and ground strap. Separate first electrodes are connected to each phase of the circuit and each electrode is disposed adjacent one end of a different hole formed in the meter base. A second electrode is disposed at the opposite end of the holes and forms a tip at each hole, thereby forming separate spark gaps with each of the first electrodes. A resistive block mounted on the outboard side of the meter base is in surface contact with the second electrode and a single ground strap is in contact with the resistive block so as to ground the meter to its socket when arcing occurs in the spark gaps.
