Wiska Bundle Kits Guide – Choosing the Right Contractor Pack
This Wiska bundle kits guide explains what is included in the Electrical4Less contractor packs, how the different combinations compare and when buying electrical accessories together makes practical sense. Our Wiska bundles combine selected COMBI junction boxes with cable glands, insulation tapes and, in some versions, electrical connectors. They are designed to simplify regular purchasing and van-stock planning for electricians who use these components frequently.
What Is a Wiska Bundle Kit?
A Wiska bundle kit is a pre-grouped selection of electrical installation materials offered by Electrical4Less. Instead of ordering each enclosure, gland and accessory separately, the customer can choose a pack containing defined quantities.
These bundles are particularly relevant to contractors undertaking repeated wiring work, maintenance, lighting installations and general electrical connections.
Our current kits are assembled around selected Wiska products, with additional accessories from manufacturers including Unicrimp, IDEAL and WAGO, depending on the bundle.
The contents of each kit are fixed by its product listing. Always check the individual bundle description before ordering, as not every pack contains the same accessories.
What Is Included in Electrical4Less Wiska Bundle Kits?
The main Electrical4Less Wiska bundles use COMBI 206 and COMBI 308 junction boxes. These are supplied in different quantities alongside compatible accessories according to the selected kit.
Wiska Bundle Kit 1 – Smaller Contractor Pack
Kit 1 includes the following products:
- 30 x Wiska COMBI 308 junction boxes.
- 20 x Wiska COMBI 206 junction boxes.
- 100 x Wiska 20mm cable glands.
- 15 x Unicrimp insulation tapes.
This provides a combination of 50 junction boxes, 100 cable glands and insulation tapes for contractors who regularly use these enclosure sizes.
See the Wiska Bundle Kit 1 product details.
Wiska Bundle Kit 2 – Larger Contractor Pack
Kit 2 contains a larger quantity of the same core product types:
- 50 x Wiska COMBI 308 junction boxes.
- 30 x Wiska COMBI 206 junction boxes.
- 200 x Wiska 20mm cable glands.
- 30 x Unicrimp insulation tapes.
This bundle may be more suitable for contractors with higher regular consumption of COMBI junction boxes and cable glands.
See the Wiska Bundle Kit 2 product details.
Wiska Bundle Kit 3 – With IDEAL Lever Connectors
Kit 3 combines COMBI enclosures and glands with IDEAL lever connectors. It includes:
- 30 x Wiska COMBI 308 junction boxes.
- 20 x Wiska COMBI 206 junction boxes.
- 100 x Wiska 20mm cable glands.
- 2 boxes of IDEAL 2-pole Gen II lever connectors.
- 2 boxes of IDEAL 3-pole Gen II lever connectors.
- 15 x Unicrimp insulation tapes.
This arrangement may suit contractors who routinely use lever connectors alongside Wiska enclosures. Connector ratings, conductor compatibility and enclosure space must still be checked for every installation.
See the Wiska Bundle Kit 3 product details.
Other Bundle Combinations
Electrical4Less also offers a larger Kit 4 with IDEAL connectors, alongside Wiska and WAGO contractor combinations for installations requiring preselected connector products.
These packs have different quantities and contents. Compare the current Wiska bundle range to confirm which combination best suits your purchasing requirements.
Why Use Wiska COMBI 206 and 308 in Contractor Bundles?
The COMBI 206 and COMBI 308 offer different enclosure sizes and cable-entry layouts, allowing contractors to keep more than one size available for routine junction work.
The Wiska COMBI 206 is a compact rectangular junction box that may be appropriate for smaller wiring arrangements.
The Wiska COMBI 308 provides a square enclosure format and different cable-entry arrangements, making it useful where the 206’s dimensions are insufficient.
Having both sizes available gives electricians more flexibility, although neither should be selected without checking internal space, cable dimensions, environmental conditions and the required connections.
For a comparison with larger COMBI models, see our Wiska COMBI junction box buying guide.
Are Wiska Bundle Kits Cheaper Than Buying Separately?
Buying materials in grouped quantities can be convenient and may offer a price advantage over ordering identical items individually. However, a bundle is not automatically cheaper in every situation.
The most useful comparison is the current bundle price against the cost of purchasing exactly the same quantities separately, excluding or including VAT consistently.
Other considerations include whether the contractor will use the full contents, how much storage space is available and whether purchasing in bulk reduces the need for repeated orders.
A smaller kit may provide better value for a business with modest monthly consumption, while a larger bundle could be suitable for a contractor using substantial quantities of the same products.
How to Choose a Bundle for Your Van Stock
Before ordering a contractor pack, review the materials used across your recent installations. This helps determine whether the quantities and product types in a bundle match your normal working requirements.
- Count how many COMBI 206 and 308 boxes you typically use each month.
- Check whether your regular cable sizes are compatible with the glands included in the bundle.
- Consider whether you regularly use IDEAL or WAGO connectors.
- Compare the quantities supplied with your normal purchasing cycle.
- Check available space for storing junction boxes and accessories.
- Compare current prices and confirm product availability before ordering.
Keeping a consistent selection of frequently used accessories can simplify stock management, but it does not remove the need to choose appropriate products for each installation.
Using Bundle Components for Outdoor Electrical Connections
Selected Wiska COMBI junction boxes provide IP66 protection when their specified membrane entries are used correctly. Compatible models may achieve IP67 using the appropriate ESKV gland arrangement, subject to the manufacturer’s instructions.
These ratings should not be confused with a guarantee that every installation is weatherproof. The cable, gland, enclosure, seal and fitting method must all be suitable for the intended conditions.
For outdoor work, contractors may also need suitable SWA armoured cable, Hi-Tuff cable or NYY-J cable, depending on the installation design.
Standard cable glands included in a bundle should not be assumed to provide SWA armour clamping. For armoured cable, use a suitable SWA termination gland and the required protective earthing arrangement.
For more detail, see our Wiska COMBI outdoor installation guide.
What Is Not Normally Included in These Bundles?
The current standard Wiska Bundle Kits 1–4 are principally based on COMBI 206 and 308 boxes, specified glands, Unicrimp tapes and, for selected kits, IDEAL connectors.
Contractors requiring additional components may need to order them separately. These could include:
- Larger Wiska COMBI junction boxes, such as 407 or 607.
- Specialist SWA brass cable glands and earthing accessories.
- Wiska venting components for suitable pressure-compensation applications.
- Additional WAGO 221 connectors.
- Alternative cable glands for different cable outside diameters.
These are examples of separately available accessories, not a statement that they are included in every Wiska bundle.
Do Bundle Kits Guarantee Compliance with BS 7671?
No. A bundle provides a selection of products but does not certify that an electrical installation complies with BS 7671.
Compliance depends on appropriate design, component selection, installation, inspection and testing. Electricians must confirm that the selected junction box, cable, glands and connectors are suitable for the actual conditions and circuit requirements.
For example, a weather-resistant enclosure may be appropriate for one outdoor installation but unsuitable for another involving additional environmental or mechanical demands.
Wiska provides technical data describing the construction and protection of its individual products. See the official Wiska COMBI technical information for an example of how the manufacturer specifies IP protection and cable-entry arrangements.
Can Electrical4Less Supply a Custom Bundle?
Contractors may need a different mix of boxes, glands and connectors from the standard kits. Electrical4Less can consider enquiries for alternative quantities or custom combinations, subject to product availability and quotation.
For example, a contractor who uses more COMBI 308 boxes than 206 boxes may want to discuss a different purchasing arrangement. Larger recurring orders may also justify reviewing the required materials together.
Contact our team with the product codes, quantities and preferred combination to request a quotation. Custom availability and pricing are not guaranteed until confirmed.
