The breaker type be it a single pole or double pole will depend on what voltage the air conditioner operates on. Once the voltage is established, the sizing of the breaker depends on what the current draw of the air conditioner is.
A 15kw heat strip typically requires a double-pole breaker with a rating of 60 amps. This allows the circuit to handle the high power requirements of the heat strip safely. Make sure to consult the manufacturer's specifications to ensure the correct breaker size for your specific unit.
To determine the appropriate breaker size for a 20 kVA heat strip, you need to calculate the current. For a 240V system, the current is approximately 83.3 amps (20,000 VA / 240V). It’s standard practice to use a breaker rated at 125% of the continuous load, so a 100-amp breaker would be suitable for this application, providing a safety margin. Always consult local electrical codes and a qualified electrician for compliance and safety.
To determine the size of the breaker needed for a 78 amp range, you typically need to use a breaker that is the next size up from the amp rating. This means that you would need an 80 amp breaker to safely accommodate the 78 amp range. However, always consult with a qualified electrician to ensure the correct breaker size for your specific electrical setup.
When installing a circuit breaker, you size the breaker based on the wire size. The breaker should be matched to the ampacity of the wire to ensure proper protection against overloads and short circuits. The device being controlled by the breaker is not a determining factor in sizing the breaker.
You will need to use #8 wire.
What size of central and heat unit do you need for 916 sq ft?
You should not have to calculate the watts of the unit. All the information that you need will be on the nameplate of the unit. It is this information that electricians use to calculate the conductor size and breaker to supply the power to the unit.
50amp but if considering the breaker cannot withstand starting current you need to size the breaker up.
For a 30 amp breaker, you will need a wire that is at least 10 gauge in size.
For a 50 amp breaker, you will need a wire that is at least 6 gauge in size to safely handle the electrical load.
A 15kw heat strip typically requires a double-pole breaker with a rating of 60 amps. This allows the circuit to handle the high power requirements of the heat strip safely. Make sure to consult the manufacturer's specifications to ensure the correct breaker size for your specific unit.
For a 50 amp breaker, you would typically need a 6-gauge wire.
To determine the appropriate breaker size for a 20 kVA heat strip, you need to calculate the current. For a 240V system, the current is approximately 83.3 amps (20,000 VA / 240V). It’s standard practice to use a breaker rated at 125% of the continuous load, so a 100-amp breaker would be suitable for this application, providing a safety margin. Always consult local electrical codes and a qualified electrician for compliance and safety.

For a 2.5-ton heat pump, you typically need a double-pole breaker rated between 15 to 30 amps, depending on the manufacturer's specifications and the unit's electrical requirements. Most commonly, a 20-amp breaker is used for a 2.5-ton unit. Always consult the heat pump's installation manual and local electrical codes to ensure proper sizing and compliance.
8 AWG is typical.
To determine the size of the breaker needed for a 78 amp range, you typically need to use a breaker that is the next size up from the amp rating. This means that you would need an 80 amp breaker to safely accommodate the 78 amp range.
