• When working on electrical systems, it is essential to turn off the power. Turn the power off at the service panel prior to working with wiring. Padlock the electrical box to prevent an unauthorized person from turning the power back on while work is being done. Carry a lock and key for this purpose.
• Use tools with insulated handles. Insulated materials such as rubber, wood, glass, and ceramic are appropriate. Stand on a dry and insulated platform. Carry a rubber mat for this purpose. Keep yourself and your clothing as dry as possible. Wear rubber soled shoes. Remove jewelry.
• Wear safety glasses.
• Be sure that the pool and equipment are properly bonded. Pay special attention to pumpmotors,switchboxes,andmetalpipes.
• Ensure that all metal enclosed equipment is properly grounded.
• Using test meters, ensure that a circuit is not electrically charged before handling wires. Be sure that the meter can withstand the voltage and current range because a meter set for a 110 VAC range will not survive if it is used on a 220 VAC circuit.
• Take care not to touch live metal equipment. Test for this using a voltmeter to see if there is a voltage between the metal housing on the equipment and the earth ground (usually a water pipe). There should not be a voltage reading. If there is, a shock can occur as the current travels to ground.
• Take care not to touch live wires or a severe shock may ensue.
• Don’t let live wires touch ground. A circuit breaker or fuse will be blown. Heaters, water pipes, and similar items should be grounded.
• Use a GFCI outlet for power around swimming pools, spas, or water. If one is not available, carry a portable one.
• Replace all worn electrical wires. Check that the insulation is in place and in good condition.
• Before working on capacitors, short circuit them or risk shock. A capacitor may be used in the start winding and the running winding of the pump motor. To discharge a capacitor, use a screwdriver to make contact between the two terminals. Be sure to wear safety goggles.
• Don’t attempt electrical work without understanding the basics of wiring, understanding wiring diagrams, and have wiring experience.
