Divide 20A by the Amps listed on the label of each fixture ballast. A T8 bulb will use an electronic ballast. They generally run 1A for four 4 foot bulbs. Try 15 four bulb fixtures per circuit and use a 20A rated switch.

Generally, you can safely connect up to 10 T8 fixtures to one 20 amp circuit. Each T8 fixture typically draws around 2 amps of current, and a 20 amp circuit can handle a maximum load of 16 amps. It's always best to consult a licensed electrician to ensure proper setup and safety measures.

How many ceiling fixtures can be on one circuit?

The number of ceiling fixtures that can be on one circuit depends on the wattage of the fixtures and the amp rating of the circuit. As a general rule, it is recommended to not exceed 80% of the circuit's amp rating to prevent overloading and ensure safety. It is best to consult with an electrician to determine the appropriate number of fixtures for your specific setup.


Can you control 10 outlets with one 20 amp GFCI outlet on one 20 amp circuit?

If each outlet draws less than 2 amps, then you could control 10 outlets with a 20 amp GFCI outlet on a 20 amp circuit. However, it's worth consulting an electrician to ensure the load calculations are accurate and the wiring is safe for the intended use.


How many laptops could you run on one 20 amp circut?

It is recommended to only connect one laptop per 20 amp circuit to ensure it operates safely and efficiently. Attempting to connect multiple laptops on the same circuit could overload it and cause the circuit breaker to trip.


Can you change a 32 amp circuit breaker to a 40 amd circuit breaker?

It is not recommended to swap a 32 amp circuit breaker with a 40 amp one without verifying that the wiring and components are rated for a higher amperage load. Consult with a licensed electrician to ensure the safety and compatibility of the circuit before making any changes.


Can you split one 30 amp plug?

No, it is not recommended to split a 30 amp plug as it can lead to overloading the circuit. It's best to use a dedicated circuit for each appliance to ensure safe usage of electricity.
