An innovative approach to connection technology
UU
Cage Clamp® is a universal clamping system for
solid, stranded, fine stranded and ferruled conductors with a range from 0.08 – 35mm time and guarantees a gastight and maintenance free connection – every time. The automatic clamping feature ensures a precise, uniform contact is made between the conductor and current bar, regardless of operator skill.
PushWire, like Cage Clamp
and maintenance free connection. PushWire connectors are used exclusively for solid and 7 stranded conductors ranging from 0.75 – 6mm The design ensures that every conductor is clamped in a separate clamping unit along the current bar.

Cage Clamp that these 3 and 5 pole connectors will safely accept 0.08mm
2.5mm conductors as well as 0.08mm
to 4mm2 flexible conductors. Operation is easy using one of the integrated orange levers that locks open, ensuring that the clamping unit is ready for insertion of the stripped wire. Closing the lever, flush with the connector housing, ensures a gastight conductor connection. Wires are thus connected or removed without using any tools. There is a test point in the housing. The rating for this compact connector is 400V, 32A.

There is a test point in the housing. The conductors are removed by holding the wire and twisting left/right while pulling on the connector, which means the connector can be re-used. Also available is a fixing carrier that is designed to secure the connectors into a junction box or onto DIN rail. The rating is 400V, 24A (41A for 3 pole version). (See fig 1 page 9)

The WAGO 243 series MICRO
PushWire connectors are designed
for small solid conductors of
0.6mm to 0.8mm diameter.
Available in 4 or 8 pole in four
different colours, they are very compact yet easy to use. The conductors are removed by holding the wire and twisting left/right while pulling on the connector. Modular in design, these connectors can be assembled onto strips using the groove on the top, with each pole effectively having 4 or 8 connections. They can then be commoned by inserting a short solid conductor. There is a test point in the housing. The rating of 100V, 6A is ample considering the size of the connector itself. Also available is a fixing carrier suitable for 4 or 6 connectors that can be either DIN rail or panel mounted.

1.5mm
to 16mm2 and rating ranging from 18A, 800V to 76A, 800V. The Cage Clamp connection technique allows stripped solid conductors to be pushed in, which is a significant cost and time saving benefit, while stripped stranded or flexible conductors are inserted by using a screwdriver to open the clamp. With their space saving design, these terminal blocks are up to 30% smaller with a conductor entry angle of less than 15° which allows easier installation in confined spaces. The comb type jumper system is based on the plug and socket principle with each terminal having a spring loaded socket in the current bar. Two slots enable alternate and staggered jumpering. Testing is carried out using the jumper socket for the test adapter, test tap or modular test connectors which are unique to TOPJOB

Safer and more reliable than the old fashioned “chocolate block”, stripped solid conductors can be pushed in while stripped stranded or flexible conductors are inserted by using the pushbutton, either with a screwdriver or by hand. There are several different fixing options including screw and nut fixing from the top, fixing with self tapping screw from top or bottom and fixing with integral snap in mounting feet. In addition, the 3, 4 and 5 pole versions are available with optional automatic earth contact. The terminal blocks are pre-marked for easy identification and each pole has a test point.

Preferred practices regarding terminations
What are the key issues surrounding compliance with NICEIC procedure and BS7671 (16th Edition) wiring regs?
Typical questions asked by installers
Should WAGO connectors be used in an enclosure?
Do they need to be fixed in an enclosure?
Does there need to be strain relief on the cable?
I’m used to screw connections ­how secure is your clamping system?
How do I release the conductor from the terminal?
In order to comply with the requirements of the 16th Edition of the IEE Wiring Regulations/BS7671, all connectors should be used in a suitable enclosure of material complying with the relevant glow-wire test requirements of BS 458-2.1. (Fire hazard testing for electrotechnical products). This will provide mechanical protection for the connectors as well as protection against dust, damp and accidental damage. Although WAGO connectors are IP20 (finger touch) with Polyamide 6.6 housing for strength and durability.
The junction box connectors do not have to be fixed down in the housing provided that the cables are secured on their way into the box. However, fixing provides a more secure and professional looking finish. (See figs 2 and 3, page 9)
Yes, there should be strain relief on the cable. This could be the cable clipped outside the enclosure or cable glands within the enclosure to prevent the cables being pulled out of the connectors. (See fig 6)
The WAGO Cage Clamp® and PushWire clamping systems guarantee gas­tight, maintenance-free connections every time. Our connectors incorporating these proven technologies have been used in industrial and building services applications worldwide. The company’s reputation is built on the high quality and proven performance of our products. For installers, this ensures complete peace of mind. (See page 2)
All WAGO connectors are re-usable. PushWire conductors are removed by pulling the conductor and twisting the connector. Cage Clamp® connections are released by using a screwdriver or pushbutton/lever operation. (See figs 1, 4 and 5, page 9)
Do your connectors comply with British Standards?
What other standards do your connectors comply with?
There’s a small cavity in a ceiling, wall or floor. Can a terminal block be fitted without the need for an additional back box?
BSI recognise and harmonise with IEC 60947, 60998 and 60999. These are European standards which relate to terminal blocks and connectors. All WAGO products conform to these standards and other international requirements.
WAGO sells its products worldwide and is therefore in constant contact with testing and approvals houses around the globe. See page 11 for full list of appropriate bodies.
Yes. When installing backless equipment, such as a domestic style luminaire, it is possible for the enclosure to be formed or completed with building material considered to be non-combustible when tested to BS 476-4. (Fire tests on building materials and structures. Non-combustibility tests for materials). Where there is any doubt that the building material does not meet this standard, the electrical connections should be shielded from the fabric of the building by a suitable electrical back-box.

Choose WAGO for peace of mind
Summary of preferred practices to ensure WAGO series products are used in accordance with NICEIC procedure and BS7671 wiring regulations
All connections must be used in
an appropriate BSI/IEC approved enclosure to provide protection of equipment against certain external influences (dust/damp) and in any direction protection against electrical contact
Fig 1
The normal installation (electrical)
has many joints and it follows that these must all remain safe and effective throughout the life of the system.
All junction boxes must be accessible
for inspection and testing unless they are buried in compound.
Every connection between conductors
and equipment shall provide durable electrical continuity and adequate mechanical strength. WAGO’s
Cage Clamp
®
is vibration proof and thermal loosening free. High quality metal and material parts are used.
Where sheathed cables are used,
the sheath must be continuous into the enclosure. The cable secured via cable glands or clips. (See fig 6)
