You are the building engineer on the job. The building manager has asked you to install some lighting. The electrical blue print shows that eight 550-W lamps are to be installed on the same circuit. The circuit voltage is 277 volts and is protected by a 20- amp breaker. A continuous-use circuit can be loaded to only 80% of its rating. Is a 20-Amp circuit large enough to carry this load? Explain your answer.
