Since the service panel has black, red, and white wires, the total voltage is 120 + 120 = 240 volts.
The service panel usually contains circuit breakers. The breakers have either a red or a black wire attached to them.
The service panel provides electricity for the branch circuits.
Usually 15 amp breaker
30 amps or greater
The neutral wire is the ground
Grounds protect us from electrocution
Service Panel has a ground wire
3 prong plug – the circular, bottom hole leads to the ground buried outside.
The Neutral Wire (White)
The neutral wire is _
Grounds protect us from
Service Panel has a

Circuit breakers open the circuit when a current in a house wire exceeds the rated current for that circuit.
The circuit breaker protects people from being electrocuted to death and protects us from burning down the house.
Circuit overloads cause the generation of heat.
Ordinary breakers are rated as 15 amps.
There are bigger breakers provided for such circuits that require 240 volts – e.g Dryers and water heaters.
Instead of circuit breakers some electrical devices have fuses. Often electric stoves have fuses.
Detects current differences in the neutral and hot wire
Should be same
If not, the internal breaker goes immediately
Use near water sources – where safety is concern
Bathroom, outdoor outlets
House hold circuits are 120 volts and are alternating current. Appliances are usually connected in parallel.
