AC Pracbox

What is a AC Pracbox?

AC pracbox is an AC circuits practical training platform that can be used to train electrical apprentices in core subjects for all major Electrotechnology courses. The AC pracbox was designed by an electrotechnology trainer with more than 10 years of experience. The design was in response to the frustration experienced due to the lack of well-maintained training equipment, missing components and disengagement in learners and trainers. No more scrounging for components or feeling embarrassed due to unmaintained and old training equipment. All components in one box – AC pracbox

When and Where Can The AC Pracbox Be Used?

The AC pracbox was designed to be used when training for UEENEEG102A, which involves solving problems in AC circuits and are core subjects in major Electrotechnology courses like UEE30811. It can also be used in secondary schools when teaching electricity in physics.

The AC pracbox is designed to be used by learners in training centres with a trainer or a supervisor present. All practical training should be carried under direct supervision in order to maximise the learning experience.

Who can benefit from AC Pracbox?



Training Organisation Manager

Well designed training equipment will increase the learner and trainer engagement

Electrotechnology Trainer

Current and relevant equipment to train your learners


Get trained with real and practical equipment that inspires you to learn more through hands-on implementation of theory


Apply the theory to practical

Features and Benefits



All components in one place

No more searching around for components or power supplies


The AC PracBox is a 465mm x 325mm x 160mm ABS box with transparent latching lid. Its lightweight (~6 kg) and comes with a handle for easy carrying.

Power resistors

Train your learners with higher currents and show them how components can get warm/hot without any damage to the components. There are 6 power resistors, 3 different 50W ones for use in single phase circuits and 3 same value 100W ones for use in three phase circuits


There are 4 different types of capacitors that you can train your learners in, motorstart, power factor correction, electrolytic and paper. All with voltage ratings between 50V to 400V


Use the inductors made with contactor coils and core to show your learners various power factors

Colour screen AC meter

Very versatile meter that will show you voltage, current, power, power factor, frequency and energy consumption, all in one screen. No need for multiple meters

Isolated supply for meter

Even though the AC pracbox doesn’t have a power supply for learners’ use, the box itself needs power and to ensure the safety of trainers and learners, we have installed an isolated supply

B22 batten holders

Use various types of bulbs to show real loads

Toggle switches

Use the 4 toggle switches to connect 3 lines and the neutral wires and turn them off and on to show the effect of imbalance on neutral current

How To Get The Best Out Of Your AC Pracbox?

The AC pracbox comes with more than 20 components plus a power supply built in and an IEC power cord. You will need to supply the learners with:

     • 4mm banana plug and

     • A method to provide the practical exercises,

       which could be in the form a workbook or through a learning platform.

    • Extra meters if you would like specific measurements

Practical Exercises

We have a collection of 30 practical exercises that can be performed with the AC pracboxes, each of which come with detailed instructions, expected readings and learning outcomes. These practical exercises start from basic testing, circuit building and transitions all the way up to fault finding and can be delivered through any platform.

This will ensure that the trainers and learners use the equipment to its maximum potential and you get your return on investment.

Peace of Mind Maintenance

We provide regular maintenance service for your AC pracboxes where we come to your facility, test all the parts and components and replace the damaged ones. This will not only ensure a long-term usage of the training equipment but also give the trainers the confidence that they will work as expected before the new class begins. Depending on your usage you may choose to have the maintenance done every term or semester.
