Callaghan Electrical Contractors are a proud preferred supplier of global industry leading JCB generators. These machines are simply put, the best in the business. All JCB generators use the most advanced technology available, with meticulous design and precision engineering. The rigorous testing each and every unit has completed before entering the market has earned the range an enviable reputation for consistent, reliable service; a perfect fit for Callaghan Electrical Contractors.


JCB’s solutions range – custom built to match your exact requirements.

This range offers solutions for all larger power requirements whether for permanent, prime or standby applications, or mobile support power.

The solutions range is custom built to your specific requirements using engines from either MTU or Mitsubishi. These engines have a superb reputation in the power generation industry.

Often specified by consultants and engineers in new build projects JCB can build sets to meet specific design criteria. Available as open units these custom designed sets are usually part of a project build where the generator is actually constructed into the building that it is providing power to. They can also be supplied ready installed into purpose built 20′ or 40′ ISO containers for external siting, where internal siting is not a possibility or noise levels are critical. The containerised versions are also easily transportable making them idealy suitable for deployment into disaster zones or civil emergency.

As with all units above 100kVA in the JCB generator range, these custom built sets can be synchronised in either a superdroop mode, which allows unlimited generators to be synchronised through a common bus bar, or through JCB’s Syncro Master system which allows up to eight units to operate in parallel.


Compact, transportable power, wherever and whenever you need it

The whole point of a small unit is transportability; a ready power source wherever and whenever you need it. So JCB make it even easier to get mobile with a range of trailers for towing behind standard automotive vehicles. Versatility is increased making this size unit a great choice for agriculture, construction, telecomms, military and residential applications.

JCB 8-45kVA generators are built around industry-recognised internal componentry, giving superior performance and maximum reliability. At their heart is a 3- or 4-cylinder Yanmar water-cooled engine, mounted on anti vibration shock absorbers. It gives great performance in a compact package.

Open or canopied, single or 3 phase, 50 or 60Hz frequency, plus various voltage options; this range of generators gives you a lot of options for tailoring to meet exact needs. Standard canopy units feature a single point lift (excluding 8-13kVA) and fork pockets for superb manoeuvrability. The JCB CP1 digital control panel is fitted as standard on all units, with the exception of the 8 and 13kVA units which feature the JCB KS1 key start system.

Powered by JCB’s world-beating innovation… the JCB Dieselmax engine is at the heart of our 65-140kVA generators

The power behind our 65 to 140kVA generators is the JCB Dieselmax engine. An incredible example of JCB innovation, the world-beating, simple design of JCB Dieselmax gives it exceptional performance, developed with heavy-duty applications in mind.

Along with unrivalled performance, these units feature, low fuel consumption for increased efficiency and low noise levels to reduce environmental impact.

In line with the rest of the range, these units are available as open or canopied, and 50 or 60Hz frequency, with a multitude of voltage options.

Fork pockets and a single-point lift on all canopy builds increase mobility, while the compact dimensions of the base frame and canopy design also optimise transportability, whether by trailer or craned vehicle.

The latest JCB innovation is a 4.8ltr version, allowing JCB to build a smaller, lighter and more compact generator delivering 6 cylinder performance from a 4 cylinder engine.

Robust and powerful with effective silencing for industrial or commercial use.

Generators do not always work on flat stable surfaces so it’s crucial that they have a high structural tolerance. This is true of all JCB generators, not just within this power range, so it will come as no surprise to find that JCB generators are mounted within a robust steel base.

As with the entire range, these units are available in both open and canopy versions. The canopied generators are designed to ensure low noise and the internal soundproofing is encapsulated to ensure long term retention delivering lower cost of ownership. Soundproof units feature a residential silencer. The open range features an industrial exhaust silencer as standard, with the option of a residential silencer.

Powering our 144-220kVA models are Iveco’s 6-cylinder, high performance engines. Standard features on this range include an oil sump extraction kit to ease engine oil change. Where fuel quality may be questionable, a pre-fuel filter is an option across the whole range, and all models have a battery charger and water jacket heater fitted as standard.
