Generators

JCB petrol generators deliver reliable site power wherever the mains cannot reach. The range covers two models: the JCB-G3600P (3.6kW/4.5kVA, 7.5hp, 224cc JCB engine, recoil start, 15L tank) and the JCB-G8000PE (7.9kW/9.8kVA, 15hp, 457cc JCB engine, recoil and electric start, 25L tank). Both output 115V and 230V simultaneously, include AVR (Automatic Voltage Regulation) for clean stable power, overload protection and low-oil shutdown. AVR output makes both models suitable for sensitive electronics as well as power tools and lighting. The G3600P runs 13 hours at 50% load (15L tank); the G8000PE runs 8 hours at 50% load (25L tank). Used by construction sites, agricultural operations and events where mains power is unavailable.

If you need quieter, lighter power for camping, caravans, events or short-term emergency backup during a power cut, see the JCB inverter generators range. It runs from 2kW to 11kW, with pure sine wave output and noise from 58 dB(A) at 25% load.

Buying Guide

Size a generator by adding up the running wattage of all equipment you need to run simultaneously, then add 25-50% headroom for motor startup surge. For a site running an SDS drill, site lighting and a radio, the JCB-G3600P (3.6kW continuous) provides comfortable capacity. For a site running a compressor, multiple power tools and lighting simultaneously, the JCB-G8000PE (7.9kW continuous) is the right choice. Both generators feature AVR regulation, producing clean AC power suitable for battery chargers, inverters and sensitive electronic equipment as well as motors and resistive loads. The G8000PE offers both 115V and 230V output simultaneously — useful for sites where 110V site tools are in use alongside 230V equipment. Always run generators outdoors or in a fully ventilated space.

Frequently Asked Questions

Are JCB generators suitable for sensitive electronics?

Yes. Both JCB site generators feature AVR (Automatic Voltage Regulation), which produces stable, regulated AC output suitable for battery chargers, laptop computers and sensitive electronic equipment as well as power tools and lighting.

What is the output of JCB petrol generators?

The JCB-G3600P delivers 3.6kW (4.5kVA) continuous output. The JCB-G8000PE delivers 7.9kW (9.8kVA) continuous output. Both output 115V and 230V simultaneously.

How long will a JCB generator run on a full tank?

The JCB-G3600P runs 13 hours at 50% load and 7 hours at full load from a 15-litre tank. The JCB-G8000PE runs 8 hours at 50% load and 5 hours at full load from a 25-litre tank.
