The issue arising with power problems when operating 110-volt construction equipment is that a good proportion of machines run on a 32 amp plug and cable, whereas the transformer is fitted with a standard 3 pin plug to fit a standard 230-volt wall socket that we’re all so familiar with in our homes.
In fact, it is rare for a transformer to break down, logically there are no moving parts to cause it to break and if the transformer is regularly PAT tested, the problem is unlikely to stem from the transformer.
Rather, when a transformer trips, blows a fuse or trips the circuit board, that’s a message, similar to a warning light on your car. It means that there’s an irregularity in the power supply, either a shortfall or surge in amps. If you could somehow bypass these annoying trips, there would be a real risk that the machine’s motor might burn out. Therefore, you need to address the problem directly by following these steps –
Change the fuse in the transformer. If that doesn’t resolve the problem, then – ?
If you are concurrently using more than one machine at the same time, use an additional lead to source the power for the other from a different ring main in another room or part of the building. Do not use a double socket to power both machines.
? Reduce the number of cables powering the machine(s).
? Do not use extension reels.
If these don’t work you will need to call an electrician to –
o Replace a Type-B circuit breaker with a type D, and maybe also,
o Fit a blue 3-pin 32-amp socket into the wall and a similar type plug onto the transformer.

In an ideal construction world all buildings would be fitted with 3-phase sockets. In any industrial or commercial setting, it’s definitely worth checking out if there’s a 3-phase socket near to where you’re working or ensuring that one is fitted before you start. 415-volt machines are less prone to tripping, they are more powerful, giving an improved outcome much quicker; customers do like improved outcomes, quicker!
