armored cable
Non metallic flexible cables must carry ground wire, but do not have hazard of short circuit causing injury from shock.

Armored steel cable can be used as a grounded connection, and will protect wires from damage. Metal can be energized from an insulation failure.

All conduit ...metal, plastic ... flexible and rigid ... must be attached to structure, and attached to enclosures, boxes.
Movement, damage and deterioration are major cause of electrical failure.

Electrical tools must be insulated.
Always best to disconnect power, but insulation failure, lack of proper grounding, grounded neutral, lack of GFCI, out-of-code wiring, generator operating without transfer switch, and other problems still pose a risk to anyone working on electric power ... even when breaker is off.

2) Set some trippers/ segments.
(identify trippers-segments below)

3) Move override switch to each position,

4) Then rotate timer dial two full revolutions.

5) Watch how load turns on-and-off to understand how to set timer
Slide switch


(a) Move slide switch to each position, then rotate timer dial two full revolutions.
Rotary switch

HB113 override switch
-OR- (b) Change or move override button, then rotate timer dial two full revolutions.
Override switches

1) Each timer has override switch

2) Move override to each position and then manually rotate timer dial to see how load turns on-off

Never assume power is OFF
Use non-contact voltage tester on timer, on wire, on outlet to see if power is present.
Press button on tester, if single beep then no power is present. If continuous beep then power is present.
Never stand on bare ground, always stand on dry boards, do not hold or touch anything metal when working on timer or water heater that has power, tape tester leads to wood sticks, never touch wet water heater, or flooded water heater, or timer that had a short or fire without turning power OFF.
