Key questions to ask before you get a bespoke power distro

Creating a bespoke power distribution unit can be quite an involved process, so generally you’ll want to save yourself as much unnecessary time and hassle as you can. One of the best ways to do that is taking the extra time to consider everything before finalising the details – including (but not limited to) power capacity, safety features, or connector compatibility. Now, we won’t go into a deep-dive into all the various aspects that need in-depth consideration – but just to get you started, here are five key questions to ask to ensure your bespoke distro does exactly what it needs to.

What power capacity you actually need

One of the most important factors in a power distribution unit is its load capacity – getting the balance right for the demands of the application in question is really important to avoid ending up with a distro that’s underpowered or one that’s unnecessarily overbuilt. To that end, it’s good idea to start by considering the total power draw of all the equipment that will be connected and factor in any potential future expansions.

Supply voltage and phase requirements also need to be taken into account. Are you dealing with single-phase or three-phase power? What’s the highest current draw expected at any point? Ensuring your distro is rated appropriately will prevent overloads and unnecessary downtime.

Which safety features are essential

As a rule, a well-designed power distro will always incorporate the right protective features. (It’s something we can advise on if you’d find it helpful here at Rubber Box.) Systems like overcurrent protection, RCDs (residual current devices), and MCBs (miniature circuit breakers) are vital for preventing faults and ensuring safe operation.

You’ll also want to consider the environment the distro will be used in. If it’s for an outdoor event or an industrial setting, additional ingress protection (IP rating) might be necessary to shield against dust, moisture, and accidental contact. Emergency shut-off switches and indicator lights can also improve operational safety, making it easier to monitor status and respond to issues quickly.

How modularity and expandability affect long-term use

If there’s a chance your power requirements could change, it’s worth thinking about modularity so that you can ensure your bespoke distro will remain equally viable in the medium to long term. Swappable output modules, additional breaker slots, and adaptable mounting options can extend the lifespan of your unit. If there’s a possibility of integrating new equipment down the line, you can save yourself a lot of time and hassle by ensuring your distro can accommodate extra circuits or higher loads. Future-proofing might cost a bit more upfront, but it’s arguably less of a hassle than needing an entirely new system in a year or two.

Where the distro will be installed

And of course, installation location matters – a distro designed for a rack-mounted setup will have completely different requirements from a floor-standing unit in an industrial environment. Space constraints, ventilation, and ease of access (for maintenance purposes) are all vital considerations that it’s good to bear in mind.

Environmental conditions will also be a crucial factor. Will the unit be exposed to extreme temperatures, moisture, or dust? If so, a higher IP rating might be necessary. If it’s being mounted in a confined space, it’s a good idea to ensure there’s enough clearance for airflow and cable management.

Why the right connectors make all the difference

It doesn’t matter how well-built your distro is if the connectors don’t match your equipment. Choosing the right plug and socket types ensures compatibility and ease of use. If your distro is going to be used in multiple locations or integrated with different power sources, you may need a mix of connections. Clearly labelling outputs and using locking connectors where necessary can also improve safety and reliability.
