Intermatic control center wiring

120 volt + 208-240 volt

Install separate ground busbar
Neutral and ground wires cannot be attached to same busbare per National Electric Code

60 amp panel: Use 6 gauge wire
80 amp panel: Use 3 gauge wire
100-125 amp panel: Use 1 gauge wire

Example: 120 volt + 208-240 volt with breakers

Breakers can fit on either side of busbar
Must use double breaker for 208-240V
Use single breaker for 120V
Intermatic control center wiring

208-240 volt 

(120V not available with this wiring)

120 Volt is NOT available with this diagram
Single-pole 120V breakers can be installed, but it is against code to use Ground wire as Neutral
Subpanel applications requiring GFCI outlet, must use either the 120-240V diagram above, or 120V diagram below

120 Volt 

(208-240V not available with this wiring)

Both Hot busbars carry 120V to neutral
Only 120 Volt is available
Double-pole 240V breakers can be installed, but will not produce 240V

120Volt and 240Volt breakers

Image shows 120Volt line and 240volt line.
Both circuits have ground wire.
Each 120 and 240 require two wires to complete circuit.
120V requires 1 hot and 1 neutral
240V requires 2 hots
Ground wires are for safety.
Read more about 240 volt

Some 240Volt lines have additional neutral wire. However, neutral not necessary to complete 240Volt circuit.
Some 240Volt lines have white and black instead of red and black

Most service boxes today have separate Neutral and Ground busbars, but these busbars are bonded together electrically, and are the same.
Illustration on left shows both Neutrals and Grounds on same side of box. In actual box, the Neutral is on right side and ground on left. Illustration shows separated neutral and ground so it is easier to illustrate wires leaving breakers.
