Louisiana Residential Appliance Installer License Prep Class: Installing the Latest Version for Mac

Are you preparing to take the Louisiana Residential Appliance Installer license exam? If so, you're in luck because we've got you covered. Our prep class is designed to simulate the actual PSI state exam and help you pass with flying colors.

First things first, let's talk about Ohm's Law. This fundamental concept is crucial when calculating electrical loads and circuits. For example, what would be the load current for a 11,000-watt electrical hot tub (spa heater) connected to a 240-volt residential service? Using Ohm's Law, we can calculate the answer as follows:

I = P/E = 11,000 watts / 240 volts = 46 A

Now that you know how to apply Ohm's Law in real-world scenarios, let's move on to another important concept: circular mil conversion. According to the NEC (National Electric Code), Table 8, Chapter 9 provides the formula for calculating this conversion:

L = Vd x CM/(2 x I x K)

Using this formula, we can calculate the maximum distance between the source voltage and a motor load given the following conditions:

* 120-volt AC

* 1 HP pump motor

* 13.8 amps FLA (full-load current)

* 12 AWG copper conductor

* Maximum voltage drop of 3%

Plugging in these values, we get:

L = 120V x 3% x 6530CM/(2 x 13.8A x 12.9) = 66 feet

Now that you've mastered circular mil conversion, let's talk about swimming pool branch circuits. When properly derated with THWN copper conductors, what size wire would be required for a load of 208 V, 3 HP, single-phase, continuous duty operation motor?

According to the NEC, a swimming pool branch circuit requires a minimum wire size of:

* 1 AWG (American Wire Gauge) for a distance of up to 25 feet

* 2 AWG for distances between 25-50 feet

* 3 AWG for distances greater than 50 feet

As you can see, calculating electrical loads and circuits is crucial when working with residential appliances. Our prep class is designed to help you master these concepts and more.
