Lever connectors are a modern, easy way to connect wires. The lever engages an internal spring-clamp mechanism that simplifies the splicing process. When the levers are lifted, the ports open, and when pushed back down, the wires are locked into place. While they are typically a little more expensive than push-in connectors, lever connectors save time and are uniquely suited for some specific applications.
We sat down with Kate Gredlics, Product Manager, and Greg Anliker, End User Experience Manager and former electrician with 25+ years of experience, to discuss the best jobs for lever connectors. They shared their top 6 jobs for lever connectors, explaining how lever connectors offer unique advantages in applications that require easy rework, conductor inspection, or frequent modifications.
Here are the top 6 jobs lever connectors work best for:
Data Centres
Lighting Installations
Smart Home Upgrades
Prefabricated Construction
Electrical Apprenticeships
DIY Projects
1. Data Centres
Large construction projects such as data centres require a lot of time and resources to be developed. Large crews spend hours assembling complex electrical work that then needs to be closely inspected. Because of this, electrical contractors working on data centres and large construction projects typically see a higher frequency and rigidity in electrical inspections and require connectors that allow them to easily verify proper installation.
Additionally, data centres support critical computing systems where reliability is crucial, and every hour of downtime can cost significant amounts of money. According to CoreSite, the data centre industry’s standard for uptime is 99.999%, or 5.25 minutes of downtime per year.
This high pressure to perform means that data centre builds are extensively scrutinised. Every part of the electrical work must be inspected to ensure proper installation. Contractors can prepare for this scrutiny by using products that provide superior ease of troubleshooting, such as lever connectors.
Lever connectors’ design helps data centre electricians prepare for inspections with:
- Transparent Inspection Window: Lever connectors’ transparent inspection window allows for immediate visual verification that every wire is fully seated in the connector, as well as being stripped to the correct length.
- Integrated Test Ports: IDEAL lever connectors include a built-in test port—the 4mm connectors having two, one in front and one in back—which permits inspectors or electricians to insert a multimeter probe into the port and verify voltage.
Lever Connectors Offer Installation Assurance
Lever connectors also provide a trusted connection in environments with a lot of vibration. Since data centres’ power usage generates a lot of heat, they employ large amounts of cooling fans to combat the potential for overheating. These cooling fans create vibrations, so lever connectors are critical for these environments. Wires need to be firmly installed so they aren’t shaken out of place. Lever connectors even the playing field, because electricians can easily see when they’re properly seated to ensure no amount of shaking will cause one of the wires to fall out and break the connection. Large complexes such as data centres employ a lot of installers, so consistent connections become possible regardless of worker skill level, helping to lower labour costs.
Lever connectors’ reliable and consistent connections also reduce labour costs, which is important for the data centre industry. Lever connectors are quick to install, and when electricians are installing thousands upon thousands of connectors in data centre installs, every second of time saved installing counts. Lever Wire Connectors from IDEAL Electrical™ are the only IEC-rated lever connectors that offer the ability to insert a solid wire without first lifting the lever—making installations a lot quicker.
2. Lighting Installations
When installing lighting fixtures, electricians often work with limited access. Ceiling fans, chandeliers, and other lighting set-ups need to be connected to overhead wiring. This means installers are working against gravity, so it can be difficult to exert pressure when pushing in wires.
Lever connectors are often best suited for these jobs. Since lever connectors’ ports have zero resistance when opened, electricians can insert wires with one hand instead of needing to push. Additionally, as long as the levers are closed, electricians can let the connectors dangle for a second while they work to get the rest of the wires installed.
Another reason lever connectors’ lack of entry force benefits workers installing lighting fixtures is the type of wire they use. Lighting installations often use flexible wire, which have many more strands than typical rigid-stranded wires. When using connectors that require entry force, the pressure applied to the wires can cause the strands to fray out against the opening of the connector. On the other hand, lever connectors allow these delicate wires to connect without causing them damage. These wires can easily be removed and reused with either solid, rigid-stranded, or flexible wire, since they are undamaged by the lack of resistance when inserting them into a lever connector’s ports.
3. Smart Home Upgrades
Today, there are around 65.5m European households equipped with a smart home system. Whether it’s a smart speaker, smart lighting, or a security system, smart devices are constantly innovating to make life easier. The European smart homes market is projected to grow to an estimated €32.12 billion by 2031. Smart systems allow for convenience, accessibility, and safety, but keeping installations up to date can be a daunting task for electricians.
Most smart home device installations need eventual updates as technology advances, typically calling for wiring that can handle circuit modifications. Lever connectors are well-suited for these modern homes. Their reusable design allows splices to be easily disconnected and reconnected, making them ideal for smart home technology, since most smart switches update over the years. Wires can easily be removed by simply opening the lever, so new technology can be implemented without struggle.
IDEAL Electrical Lever Wire Connectors can benefit smart home installations through their ability to handle wires between 0.14mm2 and 6.0mm2, which covers the majority of residential electrical circuits. The smaller wire support is great for certain smart home devices—for example, many smart home control and thermostat systems use smaller 0.82mm2 or 0.33mm2 wires.
4. Prefabricated Construction
Large commercial construction projects can take a lot of time to build, even with a large workforce. One way electrical contractors have begun to adapt to tight timelines is with a new construction strategy called prefabrication. Prefabrication means that contractors build portions of the building off-site, compressing build timelines by constructing separate items simultaneously. For example, sensitive equipment such as panels cannot be added onto a building until the roof is finished and the building is fully weathertight. However, prefabrication permits electricians to work on panels and transformers in protected areas off-site while the building is constructed. Once the main site is ready, the pieces can be fully assembled within the structure.
Lever connectors benefit prefabricated builds by being able to connect many different types of wires. They are approved for use in a broad array of permanent wiring applications. Since lever connectors support connections between wires of different types and sizes, assembly after offsite builds becomes much easier.
Commercial construction can also accrue high labour costs due to maintenance requirements, so lever connectors that carry safety certifications can help confirm the installations meet stringent safety standards. IDEAL Electrical’s 4mm connectors have a rating of 32A and 450V, whilst the 6mm lever connectors are 41A and 450V. Both sets of ratings are European IEC rated. IDEAL Electrical’s 4mm and 6mm lever connectors also support ambient temperatures up to 85°C, so electricians can maintain safety standards even when builds are assembled in extreme conditions.
5. Electrical Apprenticeships
Apprentices and learners will benefit from easier-to-install lever connectors that ensure connections and terminations are right the first time. When experienced electricians work with apprentices, gaps in skill level can create noticeable inconsistencies that can cause issues down the line for electrical installations. One common mistake apprentices can make is failing to fully seat conductors correctly. However, products that provide consistent quality regardless of skill level can solve these problems.
One of these solutions is the lever connector. Since the lever provides a repeatable, factory-set clamping force on the wire in the port every time, the skill gap between experienced electricians and their apprentices is no longer an issue. The spring-clamp mechanism eliminates variability by applying an optimal, calibrated force to the conductor every time, so the connection is less dependent on the installer’s skill. This consistent connection quality reduces the risk of loose connections that can lead to electrical hazards such as overheating. Lever connectors also allow training centres to reuse the connectors and supplies, as the wire isn’t damaged by the lever connector. Otherwise, the wire leads keep getting shorter until they are unusable.
Additionally, IDEAL’s lever connectors have features that help apprentices learn how to effectively secure wires. Their transparent inspection window allows for easy visual verification that every wire is fully seated in its port. It also helps them see the strip length is correct and consistent. 6mm2 IDEAL lever connectors also specifically feature an audible click, so the apprentice can hear confirmation that the connection has been secured.
6. DIY projects
DIY projects can take a lot of time and effort, especially for inexperienced electrical workers. When taking on a project for the first time or working alone with a limited amount of expertise, installers will benefit from connectors that make installation simple. Lever connectors allow DIYers to easily make secure connections on the first try.
The reusability of lever connectors allows for easy circuit modifications or temporary connections without cutting and re-stripping any wires. The wires can instead be released simply by lifting the levers, so if a DIY user needs to adjust a connection during a project, lever connectors reduce the ensuing workload by a significant amount.
The lever’s inspection window also makes it easier to see which wires are entering which connectors in confined spaces such as junction boxes. Additionally, due to their small size, multiple lever connectors can fit into these small enclosures where space is limited. The lever connectors’ translucent design and small size also gives junction boxes a cleaner look, which can help a more inexperienced user.
Lever connectors that offer design features like profiled sides and push-in capability also provide DIYers with a leg up. The profiled sides allow for easier grip while holding, making one-person projects take less time and effort. Lever connectors that permit solid wires to be pushed in without opening the lever first offer even more convenience. IDEAL Lever Connectors are one example of a connector with both profiled sides and IEC-approved push-in capability. The springs still provide tension in the same way as a push-in connector, so solid wire doesn’t require extra movement from the levers.
