Spine for 16A-1250A centers with fixed input is an easily installed solution that connects the worksite’s fixed-input boards to real-time Spine remote management and monitoring.

A simple way to connect a fixed-input board to Spine

Spine for fixed-input boards is a simple way to connect the worksite’s electrical network to the Spine remote management service, letting you monitor in real time power consumption, CO2 emissions, load distribution between phases, any voltage drop, and more. Proactive alarms can be set up in the service so that potential problems are caught early.

IP65 enclosure and three current transformers

The product has a sealed IP65 enclosure, from which 3 current transformers extend, clamped onto the board’s supply conductors. Inside the enclosure is a Spine One central unit and an antenna. For the Spine unit’s power supply, the product has a 1.8m connection cable fitted with a 16A plug.

Installation on the board’s supply cable conductors

The enclosure can be mounted inside or outside the fixed-input board for the best reception for the Spine 4G antenna. The current transformers are clamped onto the board’s supply cable conductors L1, L2 and L3, and the 16A power cable is plugged into the board’s 16A socket. The Spine enclosure is connected to the Spine service using a QR code.

The device places itself correctly in the Spine service

The board can be named in the Spine service with any name or ID number. The device automatically places itself in the correct spot on the riser diagram based on the details entered during setup. Read more about the service here.

Spine for 16A-1250A centers with fixed input 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 1250 A. Size the equipment by the actual simultaneous load – the sum of the nameplate ratings almost always leads to oversizing.

Where Spine for 16A-1250A centers with fixed input 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.

Spine for 16A-1250A centers with fixed input – 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, 250A Main switch module Spine.

Other details that affect the choice: weight 2,5 kg, dimensions 17,5 x 25 x 10 cm. These are worth checking already at the quotation stage.

Spine for 16A-1250A centers with fixed input – 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.

Spine for 16A-1250A centers with fixed input – 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 2,5 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.

Spine for 16A-1250A centers with fixed input – 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 501310006 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.

Frequently asked questions

Does the device fit all fixed-input boards?

Yes, the device fits all fixed-input sub boards and main boards, regardless of make or model.

Is an electrician needed for installation?

The enclosure is mounted inside or outside the board, and the current transformers are clamped onto the board’s supply cable conductors L1, L2 and L3. Installation should be carried out by an electrician, but no separate rewiring is needed.
