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.

Protect wiring from damage
Use nipper instead of pliers or screwdriver for removing staples (and nails). Do not damage cable or wires inside cable.

-Code says: Cable SHALL BE secured without damage to the outer covering. NEC sec. 336-15

Household NM-B Wires are color-coded so inspectors/ electricians can easily identify which wire is used during construction

Damp- wet locations:
For direct burial underfoot, in contact with damp soil ... or for other damp locations ... use UF-B wire ... or use plastic conduit. UF-B wire can be difficult to strip back for wiring.
Match wire size and breaker amp rating
If your home was wired by professional electrician who pulled permits, then circuit breaker and wire size will match. If manufactured home or travel trailer has not been altered by homeowner then breaker and wire size will match.

Safe maximum of amp draw on a breaker is 80% rated value of breaker.
Look at label on each load (TV, refrigerator, box fan etc). Add up total watt load on circuit. Divide the watts by the voltage on line = amps.

Main breaker terminals are still Hot when main breaker is turned off. Absolute electrocution danger when removing cover off main panel. More information below.

Use 600 volt solid copper wire only
Do not use stranded wire inside main breaker box or any permanent box.
Stranded wire can be used for connectors and plugs, but comes loose under screw terminals of breaker, switch, outlet, or timer etc when heat on wire causes expansion and contraction of wire.

Do not use extension cord for permanent household wiring
Extension cords are used for connectors and plugs only.

Install GFCI circuit breaker inside main breaker panel?
Outdoor circuits are always safer with GFCI protection, and GFCI installation might be required to meet local codes.
Caution, only 1 GFCI per circuit. So if your are going to install 120 volt plugs inside the panel (as shown lower on page) then these will be automatically protected by the 240 volt GFCI breaker.
Illustration shows 2-pole 240Volt GFCI.
The ordinary 240Volt breaker does not have white wire
The GFCI 240Volt breaker has white wire that connects to neutral busbar.

T10404 wiringT10404T with two T104 timers for filter and cleaner
Supply voltage is 240 volts that connects to Terminals 1 and 2 on Filter timer.
Both timers have a clock motor that rotates the yellow dial once per day. The dial can have up to 12 sets of trippers for 12 ON-Off periods each day. Both clock motors are connected to terminals 1 and 2 on the Filter timer.

The terminals on Cleaner timer receive no voltage unless the Filter timer is ON. This assures that pool cleaner can only run when the filter pump is ON.

 Filter pump must be ON so debris from the pool can be run through the sand filter.

T10404 wiring    Fig 2 is same as Fig 1 shown above.
Note that both the Filter Pump and Cleaner must be same voltage, either 120V or 240V.
Timer clock voltage must match the Pump and Cleaner.
The clock motors can be changed to either voltage
Buy:

Both clock motors must connect to terminals 1 and 3 on Filter Pump timer.

The pool cleaner never operates unless the filter pump is running. The wiring is designed for that purpose, so that the debris picked up by cleaner gets sent through the sand filter.
T01404 wiringEach timer on different breaker/ 2 circuit breakers
Illustration shows a method for running the filter pump and cleaner on separate circuit breakers.
This came from an email question from a fellow who was experiencing overload on 1 circuit breaker, and wanted to install second breaker to run the cleaner.
The contactor turns ON when filter timer is ON. The contactor closes circuit so cleaner timer receives power. When cleaner turns ON, it is powered from the second circuit breaker.

WH40 clock motorTroubleshoot T10404 and T10101R
-Flip circuit breaker fully off and then back on.
-Check that both clock motors are connected to terminals 1 and 2 on the Filter timer.
-Observe if both clock dials are rotating 1 revolution per day. If dials are not rotating, then clock motor is bad, unit is not getting voltage, or is getting incorrect voltage.
-Convert timer to either 120 Volt or 240 volt by changing clock motor

-Check if each clock dial has ON and OFF trippers fastened to yellow dial.
-Move both override levers to ON position. If Filter pump is OFF and Cleaner pump is OFF, then move both override levers to ON position. If Filter pump works and Cleaner pump works, then voltage is correct and wiring is correct.
-If all the above steps function correctly, observe if the trippers push the override lever back and forth between ON position and OFF position. If the dial rotates tripper past the override lever, and override lever does not change position, then most likely problem is worn trippers need to be replaced.

Wiring Tips
Keep wires straight
Use solid copper wire
If wiring terminal  or end of wire are covered with green, use emery board to clean terminal and sandpaper to clean wire.

Insdulation under screw plate

Both wires MUST be same gauge
Straighten each wire
If wire is corroded or overheated, clean the end with sandpaper and wipe with cloth.
If wire has been melted, cut back and reattach, or replace wire.
Tighten screw very tight against copper wire


Use wire connector  
Push on wire connectors
Use push-on wire connectors
3 wires/ or different gauge wires
Join wires with wire connector or push-on connector
Run jumper to screw terminal.
Buy:

Red 3P connector (shown) for 10-14 gauge wire

Fire safety/ Do not put stranded wire under screw plate
Do not install stranded wire under screw.
Problem1: picture shows 2 different gauge wires under screw plate
Problem2: Stranded wire will expand and contract and come loose under screw plate, even if it is the only wire under the screw plate
Attach stranded wire and solid wire with wire connector, and run solid copper jumper wire to screw terminal
Take photo of wires before starting.

Basic house wiring
Add black tape when White wire carries voltage (applies to 208 and 240V circuits)

With 208 and 240 circuits, both wires are Hot, and both wires carry voltage
Black tape on White wire identifies wire is Hot and not Neutral
Safe electric practice for boxes/ enclosures
For household 120-240 volt power:
-Use only approved 600 volt cables, wires, enclosures, boxes, conduit etc for household 120-240 volt.
-Extension cords are not rated 600 volt, and cannot be used for permanent in-wall wiring.
Resources Extension cord code
-Do not use makeshift, homemade boxes that are not rated for household voltage.
-Correct box must be used for application ... a light fixture or fan requires round or octagon box ... cannot use switch box, or square junction box for light fixture ... cannot use round, octagon, or square junction box for switch and outlet.
-All enclosures and boxes require a cover that is made to fit box, and must sit flat and tight against box.
-Missing knockout holes must be filled.
-Keep enclosure door or cover in place and closed to contain spark and potential fire hazard.
-Box cannot have vent holes or heat fan installed where air supply can feed a potential fire. 
-Never solder household wiring connections. High heat from resistance, caused when amperage gets pushed through the wire by voltage, will melt solder and cause potential hazard.
-Use only approved 600 volt wire connectors. Never reuse old wire connectors.
-All enclosures, wiring, conduit etc must be attached firmly to structure, and located so cannot be damaged by lawn equipment etc. and best if located away from high heat, exposure to sun. Heat will cause deterioration of electrical installations.
-Enclosures require ground wire to be present and connected to all devices, equipment etc. Metal boxes and enclosures require connection to ground wire. Plastic boxes do not require grounding.
Resources: Safe electric wiring/ for boxes and enclosures     Color code for wire

Low-voltage structural wiring (doorbell, communication, TV etc):
-Never include low-voltage 'structural wiring' inside same enclosure, conduit, raceway or box as household voltage.
-Low voltage structural wiring and household wiring must be electrically separated to prevent insulation failure from energizing low voltage wires, cause fire and safety hazard.
-Structural wiring can be run inside walls, does not require enclosure, box conduit etc except for installation convenience, weatherproofing, reliability, organization, access to splices and connections etc.
-Household 120-240 volt wiring cannot be soldered ... but low-volt structural wires can be soldered when needed.
