lockable sub center – the sub central’s supply and all outputs are protected behind a lockable door. The legs of the sub central made of aluminium can be pushed inside the center during transport and adjusted to the desired height and position on the construction site. The center has a lifting handle on top and on the sides, so it is easy to move. Thanks to its long legs and lockable door, this center is excellently suited for the construction site right from the beginning, when the center may have to be placed on rough ground. The lockable sub center is also the perfect solution for various events, where unauthorized persons must not have access to the center. The center comes standard with Spine real-time remote monitoring, which allows for the measurement of energy consumption and the setting of proactive alerts. The activation of the Spine service is quick and easy using a QR code. The center also comes with standard VM phase meters, which measure the voltage and current of all three phases, helping to avoid unbalanced loads. Phase meters have been found to be particularly useful in events where it is challenging to predict the final total load before the start of the actual event. Center is manufactured in Finland and only high-quality European components have been used in its manufacture. Spare parts can be found quickly directly from our warehouse.

lockable sub center on the worksite

Spine is a remote monitoring system. Measurement data is sent to the cloud service where it can be viewed on any device – nobody needs to travel to the site to read a meter.

The service shows electricity consumption, load distribution between phases, voltage drop and CO₂ emissions, among others. Predictive alarms can be set so a deviation is caught before it stops the work.

The same cloud service gathers every Spine unit on the site into one view, however many measuring points there are.

This model is rated 63 A. Size the equipment by the actual simultaneous load – the sum of the nameplate ratings almost always leads to oversizing.

Outputs: 1 x 63A, 2 x 32A, 2 x 16A, 6 x 16A/230V. Count the work points before choosing – the number of outputs decides how many machines one board can feed.

Where lockable sub center is used

Typical sites are construction projects, renovations, industrial maintenance and event power. What they share is that the electrical supply is temporary and the conditions are demanding.

Temporary does not mean lighter requirements. Site equipment is exposed to dust, moisture, moving and mechanical stress in a way that fixed installations never are.

Check the load distribution between phases during use. Uneven distribution overloads one phase while the others run half empty, and the usual symptom is a fuse that keeps tripping.

lockable sub center – how to choose the right model

The equipment is chosen by rated current and outputs. Start by calculating the simultaneous load and the output types needed, and choose the model on that basis.

Other models of the same type are Spine Plug & Play 16A, Spine Plug & Play 32A, Spine Plug & Play 63A, Spine Plug & Play 125A, Spine for 16A-1250A centers with fixed input.

Other details that affect the choice: weight 24,3 kg, dimensions 65×76×30 cm. These are worth checking already at the quotation stage.

Practical notes for use

Winter brings requirements of its own. Condensation forms when cold equipment is brought into the warm, and moisture inside the enclosure is a common reason for an RCD tripping with no visible cause.

Mark the equipment with the site details and keep a record of what is fed from where. On a site with several contractors that saves time at every fault-finding.

RCD protection is mandatory for socket outputs on a site. Its operation is tested with the test button at commissioning and at regular intervals afterwards.

lockable sub center – installation and maintenance

Installation and connection work is carried out by a qualified electrician. The equipment must be made dead before connection work, and the absence of voltage verified by measurement.

Place the equipment on level ground and so that it can be reached freely even when the site fills up with material. Material stacked in front blocks both use and emergency isolation.

Test the RCD with its test button at commissioning and at regular intervals afterwards. The test takes a second and is still almost always forgotten.

The unit weighs 24,3 kg. Take the weight into account when moving and lifting – damage is most often caused during transport, not in use.

Check the joints and fixings regularly during use. A joint that heats up is a sign of a fault and should be corrected before the fault spreads.

Safety and inspections

Site electrical installations are subject to the same requirements as fixed installations, and some of them are stricter. The equipment has to withstand moving, dust, moisture and mechanical stress for the whole project.

The installation is inspected at commissioning and regularly during use: enclosure, joints, the operation of the protective devices and the fact that live parts cannot be reached.

Damaged equipment is not repaired improvised on site. A cracked enclosure, a burnt terminal or a damaged socket is replaced – on a site a temporary repair almost always becomes permanent.

Document the configuration and any changes made. Up-to-date information on outputs and protection speeds up fault-finding and the next inspection.

Delivery and sizing help

We deliver the equipment together with the cables and the rest of the site power supply in one delivery, so the set is complete when it arrives on site.

Describe the whole site in your request for quotation: supply power, the outputs needed and the estimated length of the project. We size the set on that basis.

Use the product number 505010011 when ordering and when asking about spare parts. It identifies this exact model, which matters when the same series comes in several sizes.

We also help with the sizing. If you are unsure about the size or the number of outputs, ask us – equipment sized wrong costs more than equipment chosen right the first time.
