Faithfull 5kVA 110V site transformer with two 16A and one 32A outlets. IP44-rated GRP case, thermal overload protection, and a BS-approved 13A rubber plug. Built for powering industrial tools on site.
The Faithfull 5kVA transformer is a site-ready 110V unit built to keep your tools running safely wherever mains 240V power needs stepping down. Whether you’re on a construction site, in a warehouse, or working somewhere that demands 110V supply, this transformer handles the job without any fuss. Three outlets give you real flexibility: two 16A sockets for your standard site tools and one 32A socket for heavier equipment running at the same time.
The GRP case is rated to IP44, which means it shrugs off rain, dust, and the general punishment of a working site without complaint. It’s a solid enclosure that won’t split or crack when something gets dropped on it, which on most sites is less a possibility and more a certainty.
Faithfull 5kVA Transformer Safety Features
Safety on 110V equipment matters, and this unit doesn’t cut corners. A re-settable thermal overload protection function kicks in if the unit gets pushed too hard, protecting both the transformer and your tools. Rather than blowing a fuse and leaving you hunting for a replacement mid-job, it trips and resets, keeping downtime to a minimum.
The transformer comes fitted with a rubber cable and a BS-approved 13A rubber plug, so it’s ready to go straight out of the box. No need to fit a plug or source a cable separately, which is one less thing to sort before you can get started.
IP44 Rating Explained
IP44 means the unit is protected against solid objects over 1mm and water splashing from any direction. That covers most outdoor working conditions, from light rain to dusty interiors. It’s not designed for full submersion, but for typical worksite use, the rating more than covers what you’ll throw at it.
If you regularly run multiple 110V tools at once, having a 5kVA transformer with three outlets on site makes a genuine difference to how smoothly the day runs.
Pro Tip: Always uncoil the supply cable fully before use, as a coiled cable under load builds heat and can cause nuisance tripping of the thermal overload, even if the transformer itself is well within capacity.
This transformer is used wherever a 110V supply is needed on site. That covers general construction, groundworks, fit-out, refurbishment, and utility maintenance. It powers angle grinders, drills, circular saws, SDS hammers, and other 110V site tools without issue. The 32A outlet makes it suitable for larger equipment such as site lighting rigs or more powerful single-phase tools that draw a heavier current.
It works equally well indoors and outdoors, and the IP44 rating means it can be left near entrances or in covered outdoor areas without concern. Electrical contractors, groundworkers, and general builders all use units like this as standard site kit.

Not suitable for: Not suitable for use with 110V heaters or other equipment requiring a continuous full load. This transformer is rated for intermittent tool use, not sustained high-draw applications.
Connect the transformer to a standard 240V mains supply using the fitted 13A rubber plug. Fully uncoil the input cable before switching on to prevent heat build-up. Plug your 110V tools into the relevant outlets, keeping track of your total combined load against the 5kVA rating.
If the thermal overload trips during use, switch off and disconnect tools, allow the unit a few minutes to cool, then reset using the overload button before reconnecting. This is normal behaviour when the unit has been pushed close to its rated capacity and is not a fault.
Position the transformer on a stable, level surface close to your work area
Fully uncoil the input cable before connecting to mains power
Plug the 13A rubber plug into a standard 240V mains socket
Connect 110V tools to the 16A or 32A outlets as appropriate for their draw
Monitor total combined load and keep within the 5kVA rating
If the thermal overload trips, switch off tools and allow the unit to cool for a few minutes
Press the reset button to restore power, then reconnect tools
Can I run multiple tools at the same time from this transformer?
Yes, you can use all three outlets simultaneously, but the combined load of all connected tools must not exceed the 5kVA rating. Check the wattage of each tool and add them up before running everything together. Exceeding the rated capacity will trip the thermal overload.
Is this transformer safe to use outdoors in wet conditions?
Yes. The GRP case is rated to IP44, which covers rain and water splashing from any direction. It is suitable for typical outdoor worksite conditions. It is not designed for immersion or prolonged exposure to standing water, so keep it off the ground during heavy rain if possible.
The Faithfull TRAN5 is a 5kVA centre-tapped 110V site transformer built to BS EN 61558 standards for site use. The enclosure is manufactured from glass-reinforced polyester, providing impact resistance and electrical insulation in a lightweight housing. The thermal overload protection is re-settable, avoiding single-use fuse replacement on site. Input is 240V via a fitted BS-approved 13A rubber plug, with 110V output across two 16A and one 32A CTE sockets.
