AC Pracbox: Training Kit for Teaching and Assessing AC Theory

UEEEL0020, the AC theory subject, is the toughest for electrical apprentices but essential for understanding AC circuits. Trainers struggle to cover all the content, often leaving practical training behind. That’s why we’ve packed all necessary components into one box. This ensures compliance, saves setup time, and fully engages learners, helping them grasp AC fundamentals effectively.

Key Features

Innovative Features of the AC Pracbox

The AC Pracbox includes power resistors, capacitors, lamps, and real inductors for diverse practical exercises. It features a built-in single-phase power supply, saving space and costs. The intuitive power meter displays True Power, Voltage, Current, Power Factor, Frequency, and Energy on one screen for easy, detailed discussions.

Ease of use

Since we have chosen everything in the AC Pracbox from the unit of competency’s performance requirements, you won’t need to adjust your training to the equipment. The equipment will fit perfectly into your curriculum, making it easy to use and substantially reducing preparation time.


Ideal for the following subjects:

  • UEEEL0020
  • UEENEEG102A (superseded)


Ensuring Compliance with the Training Package:

When designing the AC Pracbox, we chose the components based on all the performance requirements of the UEEEL0020 unit of competency—performance criteria, performance evidence, and range of conditions. This gave us confidence that any practical activity conducted with the AC Circuits Trainer would automatically ensure compliance.

Bridging Theory with Practical Application:

The AC theory subject is very theory- and math-heavy, which is daunting for most electrical apprentices as they are often kinesthetic learners. The AC Pracbox helps learners understand complex theoretical concepts in a practical way, engaging them and bridging the gap between theory and practical applications.

Substantial time savings:

Historically, the trainer would have had to piece together components like resistors, capacitors, inductors, meters, power supplies, etc., to demonstrate the subject’s practical aspects. This is time-consuming and hard to replicate and follow. Since the AC Pracbox has all the required components in one place, organised neatly and intuitively, the trainer saves a substantial amount of preparation time and provides a consistent and repeatable learning experience for the learners.

What Our Customers Say

Frequently asked questions

Yes. In order to keep the weight of the equipment light, we decided to not include the power supply in it so you will need an external extra low voltage power supply.
They will glow brighter as you would expect. We have specially chosen 42V lamps that will not get damaged when used in star or delta connection as long as used with the ELV supply.
No. The IEC cable at the back of the equipment supplies power to the meter.
A real inductor also has a resistive component, which will not let you have a perfect 90 degree phase shift between current and voltage.

If you only have single phase power you will only be able to do the single phase practical exercises, but to do three phase exercises you will need a 3 phase ELV supply. We can offer you Portaphase, which is a single to three phase ELV power supply
