Consider a branch circuit for 9W fixed electric space heater w/ 5.1 Amp blower motor 230 Volt 3-phase What is an adequate overcurrent protection size rating?

Consider a branch circuit for 12kW fixed electric space heater w/ 5.2 Amp blower motor 208 Volt 3-phase What is an adequate overcurrent protection size rating?

Select all the true statements from the following options:

Consider the following three-phase short circuit: With  A. 1000 kVA Transformer with 480V, 3Ph, 3.5% Z B. 25′ – 500kcm copper, 3 single conductor 6 per phase service entrance in steel conduit C. 2000 A switch with 2000 A fuse x1 Fault X1 D. 400 A switch with 400 A fuse E. 50′ – 500kcm copper, 3 single conductor feeder cable in steel conduit x2 Fault X2   Using Point-to-Point calculation (using the given impedance at 100%) The total current for short circuit sym RMS at Fault X1 is [IscRMSx1] The total current for short circuit sym RMS at Fault X2 is [IscRMSx2]

What is the demand factor (%) for a Household with 5 appliances less than 3½ kW Rating

Consider a 10-unit office building where each unit contains one A/C rated at single phase 3hp 230V The full load current for one would be: [flc1] One motor load would then be: [loadVA] The total load for all these A/C would be: [totalLoad]

According to: For a 100,000 ft2 school if the initial calculated load was 1,400,000 VA the calculate the overall load is:

In the newborn nursery, which infant should the nurse assess first?

You are the nurse on a surgical unit. Which of the following patients should you prioritize for assessment and intervention?Patients:A post-op patient who has not voided in 8 hours.A patient who is 2 days post-op with a surgical dressing saturated in serosanguinous fluid.A newly admitted patient complaining of throat tightness and itching after the first dose of an IV antibiotic.A patient who is requesting help to the bathroom and is a fall risk.Determine which patient needs immediate assessment and explain the rationale using the ABCs and safety principles.
