1. An electrical system, comprising:
a three-phase electric power source, wherein the three-phase electric power source comprises a second upstream busbar disposed between and extending in parallel to a first upstream busbar and a third upstream busbar;
a meter socket; and
a pair of straps, the pair of straps including a first strap and a second strap that are structurally mirror image with each other, wherein each of the first and second straps comprises:
a first end, wherein the first end comprises a hole and is connectable to the meter socket by a respective first fastener through the hole; and
a second end, wherein the second end comprises a first slot with an opening and a second slot with an opening, and wherein the opening of the first slot is opposite to the opening of the second slot;
wherein, when the second strap is connected to the third upstream busbar, the second end of the first strap is connectable either to the first upstream busbar by a second fastener through the first slot of the first strap, or to the second end of the first strap is connectable to the second upstream busbar by a third fastener through the second slot of the first strap, and
wherein, when the first strap is connected to the first upstream busbar, the second end of the second strap is connectable either to the second upstream busbar by the third fastener through the second slot of the second strap, or to the third upstream busbar by a fourth fastener through the first slot of the second strap.
