Three-Phase & Power

Three-Phase Electrical Conversion

A large electrical conversion at a courtyard of cottages, carried out alongside a new supply from the National Grid.

The project

Our customer asked us to carry out a very large electrical conversion at their courtyard of cottages. The work went hand in hand with a new supply from the National Grid, and the power changeover had to happen over a two-day period, with around 14 new connections to make. These were a mix of supply arrangements, including three-phase.

The new incoming supply itself was the network operator’s work. Our part was the electrical conversion on site, preparing the cabling and coordinating with National Grid and Octopus Energy so each stage lined up.

How we approached it

Around 14 new connections, a mix of supplies including three-phase

New cables laid out in advance of the National Grid work, following Rich’s plan

Preparing ahead

Rich planned for the new cables to be laid out ahead of the National Grid work, reducing what had to be done on the day and helping get a quicker turnaround.

Coordinating the changeover

We liaised with National Grid and Octopus Energy so our connections fitted around their work across the two days.

Looking after residents

One elderly resident’s meter installation was due on the second day, after the power was cut. The team worked hard to make sure she wasn’t left without power.

We had the guys at Boxt carry out a very large electrical conversion at our courtyard of cottages which involved a new supply from the National Grid. It was a big undertaking but they managed it very professionally and frankly went further than expectations. The power changeover had to happen over a two day period and there was around 14 new connections to be made, some 2-phase some 3-phase. Rich had a plan to layout new cables ahead of the National Grid work in order to reduce work on the day and get a quicker turn around. They liased with the National Grid and Octopus energy. They even went the extra mile when a meter installation for one elderly lady was due on the second day after the power was cut. They worked hard to make sure she wasn’t without power.

Guys I can’t thank you enough for your professionalism and hard work.
