Distribution box 16A THK316/6/10 – lightweight and durable 16A power distributor with 10m power connection cord for construction site use.

Distribution box 16A THK316/6/10 on the worksite

A distribution box is the outlet point closest to the work. It draws power from a larger board and provides sockets for hand tools, lighting and dryers where the work is happening.

The point is to keep extension cords short. A long cord causes voltage drop and gets in the way – a box near the work solves both.

This model is rated 16 A. Size the equipment by the actual simultaneous load – the sum of the nameplate ratings almost always leads to oversizing.

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

Where Distribution box 16A THK316/6/10 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.

Distribution box 16A THK316/6/10 – 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 Distribution box 16A THK316/2/10, Distribution box 32A TAS32/1/K, Distribution box 16A TAS16/1, Distribution box 230V THK316/6/20, TSR-HUB32 Distribution box.

Other details that affect the choice: protection class IP44, supply cable 10 m H07RN-F 5 x 2,5 mm², weight 4,8 kg, dimensions 26 x 26 x 21 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.

Distribution box 16A THK316/6/10 – 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 4,8 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 5000316 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.
