Looking for a reliable power solution for your construction site or workshop? We've been examining the Faithfull Site Transformer, and it appears to be a solid choice for powering industrial tools safely and efficiently.

This transformer converts 240V mains power into two 110V outputs, which is the standard voltage for many professional power tools in the UK. The unit handles up to 3.3 kVA intermittently or 1.65 kVA continuously, giving you flexibility depending on your needs.

Faithfull Site Transformer

The IP44-rated waterproof case stands out as a practical feature for outdoor work. Customers appreciate the thermal overload protection, which automatically shuts down the unit if it gets too hot. The twin 16amp outlets allow you to run two tools at once without needing multiple transformers.

Users rate this transformer highly, with many noting its robust build quality and reliability on job sites. Some mention it's quite heavy, which is expected given its industrial-grade construction. A few buyers point out that it's not suitable for 110V heaters, so you'll need to keep that limitation in mind.

Overview of the Faithfull Site Transformer

 

This transformer is built to power industrial tools on construction sites and outdoor work areas. It takes standard 240V mains power and converts it to 110V through two 16-amp outlets, letting you run two tools at once.

The unit sits in a weatherproof case rated to IP44 standards. This means it handles water splashes and dust reasonably well, though it's not fully submersible. The case weighs about 14 kilograms, which is expected given its heavy-duty construction.

Safety features include thermal overload protection that resets itself if the transformer gets too hot. It comes with a 2-metre rubber cable and a BS-approved 13-amp plug. One important limitation is that it has different ratings for intermittent versus continuous use. The 3.3 kVA rating only applies when you use it for 5 minutes on and 15 minutes off. For continuous operation, it drops to 1.65 kVA. You also can't use it with 110V heaters.

Reliable Power for Industrial Tools

 

This transformer steps down from 240V mains to 110V, which is the standard voltage for professional power tools on building sites. The 3.3 kVA intermittent rating means it can handle high-demand tools for short bursts, though the continuous rating drops to 1.65 kVA for extended use.

The twin 16-amp outlets let you run two tools at once from a single unit. This works well for smaller sites where multiple trades need power access.

Key limitations to consider:

  • The duty cycle requires 15 minutes of rest after every 5 minutes of full load use
  • Not compatible with 110V heaters
  • Performance decreases in temperatures above 20°C

 

The thermal overload protection automatically cuts power if the unit gets too hot, which prevents damage but can interrupt work. Buyers generally appreciate this safety feature despite occasional nuisance trips when pushing the transformer too hard.

Durability and Weatherproof Design

 

The heavy-duty GPR case on this transformer is built to handle tough worksite conditions. It carries an IP44 rating, which means it offers protection against water splashes and dust. This makes it suitable for outdoor use in most weather conditions.

The case feels solid and appears well-constructed for industrial environments. However, buyers should note that IP44 doesn't mean fully waterproof or submersible. It will handle rain and wet conditions but shouldn't be left in standing water.

The thermal overload protection is a useful safety feature that resets itself if the unit gets too hot. The 2-metre rubber cable with a BS approved 13 amp plug adds to the overall durability. At 14.2 kilograms, the weight suggests robust internal components, though this does make it less portable.

Safety Features and User Protection

 

The transformer comes with re-settable thermal overload protection that stops the unit from overheating during extended use. This feature helps prevent damage to both the transformer and connected tools when power demands get too high.

The IP44-rated waterproof case offers solid protection against dust and water splashes. This makes the unit safer to use on construction sites where exposure to the elements is common.

The included 2-metre rubber cable comes with a BS-approved 13-amp rubber plug, which meets British safety standards. However, at 14.2 kilograms, the transformer's weight makes it less portable than lighter models, though this heft comes from the robust construction that provides durability and protection.

Flexible Twin Outlet System

 

The dual socket setup offers practical flexibility for running two 110V tools at the same time. Both outlets deliver 16 amps each, which means you can power multiple pieces of equipment without needing separate transformers.

This is particularly useful for site work where you might need a drill and a saw running simultaneously. The sockets are clearly labelled and easy to access on the unit's front panel.

One limitation to keep in mind is the continuous rating of 1.65 kVA. Whilst the intermittent rating reaches 3.3 kVA, you'll need to manage which tools you run together to avoid overloading the system. The thermal overload protection will shut things down if you push it too hard, which is good for safety but can interrupt your workflow.

Set-Up and First-Time Use

 

Getting this transformer ready for work doesn't require special skills or complicated procedures. The unit arrives as a complete package with everything needed to start powering tools straight away.

Installation Process

 

The transformer comes with a 2-metre rubber cable already attached, ending in a BS approved 13 amp plug. Simply plug it into a standard 240V mains socket to get started. The unit weighs about 14 kilograms, which makes it stable once positioned but heavy enough that moving it around the site requires some effort.

The waterproof IP44-rated case allows use in outdoor conditions without concern for light rain or dust. However, it should be placed on a stable, level surface away from standing water. The case design keeps the internal components protected whilst providing access to the two 110V outlet sockets on the front panel.

Operating Guidelines

 

Both 16 amp sockets can power tools at the same time, but the total load should not exceed 3.3 kVA combined. This equates to about 30 amps total across both outlets at 110V. The thermal overload protection will trip if the transformer gets too hot from excessive use, which prevents damage to the unit.

When the thermal protection activates, allow the transformer to cool down before resetting it. The reset mechanism allows work to resume without professional assistance. Running the transformer at maximum capacity for extended periods should be avoided, as this generates more heat and increases the chance of thermal shutoff.

The frequency is fixed at 50 Hz, which suits most UK and European tools designed for 110V site power. Tools from North America that expect 60 Hz may run slightly slower than intended.

Warranty and After-Sales Support

 

The Faithfull transformer comes with a one-year manufacturer guarantee. This covers defects in materials and workmanship under normal use conditions.

The warranty period is standard for industrial power equipment in this price range. If you encounter issues, you'll need to contact Faithfull directly through their customer service channels. The company has been in the tools and equipment business for many years, which means they have established support systems.

One limitation is that the warranty doesn't cover damage from misuse or using the transformer with incompatible equipment like 110V heaters. Normal wear and tear also isn't included.

Plus Points

 

The transformer delivers solid performance for powering industrial tools on job sites. The dual 110V outlets are particularly useful, letting you run two tools at once without needing multiple transformers. This saves time and makes the unit more practical for busy work environments.

The IP44-rated waterproof case stands up well to outdoor conditions. It provides good protection against dust and water splashes, which matters when working on construction sites or in unpredictable weather. The GPR enclosure feels robust and built to handle regular site use.

Safety features are well-implemented. The thermal overload protection resets itself when it trips, so you don't need to replace fuses or components. The heavy-duty 2-metre rubber cable with a BS-approved 13 amp plug adds another layer of protection for operators.

At 3.3 kVA capacity with 16 amp sockets, the unit handles most standard industrial tools without issue. Users report it works reliably with various equipment, including American 110V tools and machinery like CNC devices.
