TSR-HUB 63A Spine Generator is an intelligent worksite distribution board that connects directly to the generator’s 63 A outlet. All power produced by the generator passes through the unit, and the integrated Spine system keeps the generator’s load at a safe level automatically — without constant supervision.

Who is the TSR-HUB 63A Spine Generator for?

Built for temporary power setups where electricity is produced by a generator: construction sites, events, and industrial sites with short-term power distribution needs. It’s especially suited to sites where the load varies throughout the day and safe generator operation needs to be guaranteed without anyone monitoring the load by hand.

All generator power through one board

The unit is a HUB 63A worksite board that takes in the generator’s full output. Because all power flows through this single board, the system sees the whole load — not just part of it — and can react reliably to changes in load.

TSR-HUB 63A Spine Generator: smart load management prevents underloading

The integrated Spine system controls two 16 A outputs on the board. When the board’s total consumption — i.e. the generator’s load — drops below the optimal level, Spine automatically switches on an auxiliary load through the contactor-controlled output. Once the main load rises again, the auxiliary load switches off automatically. An auxiliary device, such as an electric heater, is connected behind the controlled output.

Why too light a load is harmful to a generator

Running a generator on too light a load can cause several operational and mechanical problems:

• Carbon buildup and wet stacking, when combustion temperature stays too low
• Poor combustion and increased smoke
• Reduced efficiency and higher fuel consumption
• Diluted engine oil and premature engine wear
• Unstable voltage and frequency regulation

By maintaining a stable minimum load, the keskus improves the generator’s reliability, efficiency, and service life.

Commissioning without separate installation work

Commissioning is simple: connect the board’s supply to the generator’s output and plug your equipment into the outputs you need. No rewiring or site-specific setup is required — the board is ready to use as soon as it’s connected.

TSR-HUB 63A Spine Generator is part of the Spine remote monitoring system

Beyond load management, the board provides real-time data, remote monitoring, and predictive alerts.

This enables predictive maintenance and improves uptime even when no one is on site.

TSR-HUB 63A Spine Generator 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.

Where the product 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.

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 16,5 kg, dimensions 66 x 37 x 25 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.

TSR-HUB 63A Spine Generator – 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 16,5 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.

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 505010040 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

How does the TSR-HUB 63A Spine Generator prevent generator underloading?

When the generator’s load drops too low, Spine automatically switches on an auxiliary load through the controlled 16 A output. Once the main load rises again, the auxiliary load switches off.

Does commissioning require site-specific programming?

No. The board connects directly to the generator, and no separate rewiring or programming is needed.

What can be connected to the controlled output as an auxiliary load?

An auxiliary device, such as an electric heater, is connected behind the controlled 16 A output and switches on and off automatically based on the load.

Can I see the generator’s load remotely?

Yes. The board is part of the Spine remote monitoring system, which shows the load in real time and sends predictive alerts.

Is the board easy to move between sites?

Yes. The board weighs 16.5 kg, so it can be moved and installed on a new site without any lifting equipment.

What is the product number?

The product number is 505010040. You can use it for orders, quote requests, and spare-part enquiries.
