The SPD60 protection device includes two black wires and one white Grounded/Natural wire. The recommended place of installation is at the electrical panel servicing the load. Since surge protectors work by forcing the voltage spikes to ground, it is imperative that proper grounding be provided as required by local electrical codes.

For 120/240 VAC installations, connect each black lead to each of the hot lines and the Grounded/Neutral white wire to the neutral bus bar as shown in the figures.

For 120VAC installations, connect both black leads to the line (hot) and the Grounded/Neutral white lead to the neutral bus bar. This type of installation is commonly found at individual pieces of equipment.

Connection may also be made to the neutral/ground bus bar if no separate ground bus bar is provided.

All conductor lengths should be as short as possible and bends should not be sharp; a 4″ bend radius or wider is recommended.

For best performance use #12 AWG leads, 240V, 20A, 2 pole circuit breakers.

The SPD60 surge protector can be installed by removing a knockout from the disconnect or the panel box, inserting the nipple end and the wires of the surge protector through the exposed hole and tightening the retaining ring nut. These devices can also be installed using the tabs at the top of the housing and sheet.
