Merrill Single Phase Lightning Arrestors - 120V or 240V

$27.00

TO BE USED WITH 120 VOLT OR 240 VOLT SINGLE PHASE POWER
 
Purpose
The lightning arrestor is designed to protect motors and controls from voltage surges caused by lightning, switching loads, or power line interferences. Surges of 500 volts or more are directed to ground by the lightning arrestor. Although the arrestor may or may not take repeated surges, no arrestor can withstand a direct lightning strike or a surge of unusually high voltage.

Application
The Heavy-Duty Models lightning arrestor have Threads and Nut to Attach to Electrical Panel or varieties of enclosed motor controls.
Including:
WELL PUMP CONTROLS (2 WIRE OR 3 WIRE MOTORS)
1. Pressure Switch
2. Control Box
3. Both the pressure switch and control box
Note: Pressure switch arrestor location offers the best water system protection, if only one lightning arrestor is used.
 
WARNING: It is very important that all electrical work be done properly. Therefore, only a qualified electrician or electrical service man should perform the initial hook-up and any electrical service thereafter! All local electrical codes must be followed.

Check a Lightning Arrestor with an ohmmeter
Lightning arrestors have a unique feature unlike other secondary lightning arrestors in that they can be checked with a conventional ohmmeter.
 
With arrestor removed from circuit:
1. Set selector knob on ohmmeter to RX100K.
2. Connect both black "lightning arrestor" leads to one ohmmeter lead.
3. Connect white "lightning arrestor" lead to the other ohmmeter lead.
4. Resistance should read infinity (00). If a resistance reading other than infinity (00) is attained, the "lightning arrestor" should be replaced.
