Refresh Your IEC Electricity Kits for 2027: School Stocktake Guide

Refresh Your IEC Electricity Kits for 2027: A School Stocktake Guide

Eight electricity kits in the cupboard should mean eight groups ready to begin. But one missing switch, an incomplete lamp selection or components borrowed between cases can leave a practical short of equipment.

Before ordering new class sets for 2027, take a closer look at the kits your school already owns. A targeted replenishment order can restore missing components and make it clearer where additional equipment is genuinely needed.

At Wiltronics, we supply IEC electricity kits and replacement parts. This guide helps teachers and laboratory staff turn an end-of-year stocktake into a practical purchasing list.

---

Start with the kit model and the lesson

Record the model number on each kit and locate its matching contents list and experiment instructions. Similar-looking cases may contain different configurations, so avoid treating every IEC kit as identical.

Next, choose the first electricity practical planned for 2027. Lay out the equipment required for one group using that kit’s instructions.

This gives you two useful checks:

• Is the kit complete? Compare its contents with the correct inventory.
• Is the lesson covered? Confirm that each group has the components required for that specific activity.

A kit can contain plenty of equipment and still be missing the one component that a scheduled lesson needs.

Count complete working sets

Use a simple record for each case:

Keep missing items separate from suspected faults. An absent lamp is a purchasing issue; a lamp that did not illuminate during a lesson is an observation that needs assessment before deciding what to replace.

Refer equipment needing assessment through your school’s usual process.

Replacement parts worth checking

Lamp supplies

Our IEC Electricity Kit lamp pack contains ten 2.5V and ten 12V MES lamps.

Record the required ratings separately when checking your kits. A combined total of twenty lamps does not tell you how many of each type are available for the next activity.

When preparing the order, match the lamp requirements to the kit instructions. Count the supply of each rating against the planned lessons rather than assuming every lamp in the vial serves the same purpose.

---

Switches

The IEC Electricity Kit Switch is available as a separate item.

Check each case for the switch required by its contents list. If staff have borrowed switches between kits during the year, return them to their assigned cases before calculating the shortfall. Otherwise, the same missing item can appear on several teachers’ lists.

---

Copper wire

Our IEC Electricity Kit Copper Wire Roll is 100m of 0.2mm-diameter wire.

Plan wire quantities around the activities in your instructions. Record the specified wire type as well as the diameter; do not select a substitute solely because the roll looks similar.

For activities that consume cut lengths, estimate demand across all classes before the next replenishment order. Reusable apparatus and consumable wire need different quantity calculations.

---

Coils and cores

For lessons using these components, check the IEC Electricity Kit Coils for U/I Core and Plain Iron Cores, Set of 3.

Record the exact component required by the existing kit. Confirm the intended coil and core arrangement before ordering, rather than treating all electromagnetic components as interchangeable.

Work out the shortfall before buying

Consider an illustrative class of 24 students working in groups of three. Eight groups need eight complete setups for a simultaneous practical.

If your department owns eight kits but two are missing the required switches, the immediate purchasing question is whether the correct replacement switches will restore those setups. It is not automatically an order for two whole kits.

Now check the timetable. If a second class needs another eight setups at the same time, replacing those switches will not resolve the larger capacity gap.

Separate your order into:

1. Parts needed to restore existing sets.
2. Consumables needed for planned activities.
3. Additional kits needed for simultaneous classes.

This makes the reason for each purchase easier to explain when submitting a budget request.

When a new kit makes sense

A new kit may be appropriate when the department needs more simultaneous setups or a teaching capability that its current equipment does not provide.

The IEC Standard Electricity Kit in Aluminium Case is for DC and AC theory. It includes a power supply, three digital meters, components, cables and an experiment book.

Compare the current contents with your lesson requirements before choosing a kit. For older equipment, record its model and condition so that replacement parts can be assessed against a complete new setup.

---

Finish with a clear handover

After replacements arrive, reconcile them against the stocktake and return each item to its assigned case. Update the inventory and note any outstanding assessment or purchase.

Keep a master record outside the cases. This helps the next teacher or laboratory staff member see what is ready, what is missing and which order is expected to resolve the gap.

Frequently asked questions

Can we buy IEC electricity kit parts separately?

Wiltronics has individual replacement parts, including switches, lamps, wire, coils and cores. Check the exact kit model and required component before ordering.

Should we replace every kit that is incomplete?

Start by identifying the missing parts. Compare the cost and suitability of restoring the existing kit with the need for additional or different equipment. Incomplete and unsuitable are different problems.

How many kits does a class need?

Count the groups that need complete setups at the same time. A demonstration or rotating station arrangement has different requirements from a practical where every group works simultaneously.

Should we order spares for the whole year?

Base the quantity on planned activities, previous use and storage capacity. Keep confirmed requirements separate from estimates for lessons that have not yet been scheduled.

What should we send with an enquiry?

Include the kit model, photographs or part codes where available, quantities, the planned activities and your required delivery date.
