Log in to access trade discountsThis petrol generator gives you 110V and 230V from one 212cc four-stroke engine, mounted in a tubular steel frame on anti-vibration mounts. A yellow 16A socket supplies 110V site tools, and a blue 16A socket supplies 230V equipment, with a selector switch to set the output. A separate 12V output charges batteries.
A 230V-only generator needs a separate site transformer before it can run 110V tools. That means one more heavy item to carry, extra leads across the work area and another piece of kit to inspect. This generator has its own yellow 110V socket, so standard site tools and leads plug straight in.
Yellow 16A 110V socket: takes standard 110V site tools, task lights and extension leads without a separate transformer.
Blue 16A 230V socket: runs 230V equipment fitted with blue industrial plugs, or UK 3-pin plugs through an adaptor lead.
Voltage selector switch: sets the AC output to 230V or 110V to match the job.
Automatic voltage regulator: holds the output voltage steady as loads switch on and off, which protects chargers and electronic controls.
2700W continuous output: runs site tools, lighting and chargers for hours, with 3000W available for short start-up peaks.
Low oil pressure shutdown: warns of low oil and stops the engine automatically before damage is done.
Tubular steel frame: protects the engine and control panel from knocks in the van and on site, while anti-vibration mounts reduce shaking.

Builders, groundworkers and utility crews use this generator on plots, roadworks and small works where there is no temporary supply yet. It suits teams running standard 110V site tools who also need 230V for chargers or a laptop. Operators should understand load limits, the voltage selector and safe refuelling.
Running 110V drills, saws and grinders on plots before the temporary site supply is connected.
Powering 110V task lights and festoon lighting for early starts and late finishes.
Switching to 230V to run battery chargers and a site laptop at the end of the shift.
Supplying power for reinstatement, utility and small works jobs away from buildings.
Charging 12V lead-acid batteries on plant and vehicles through the DC output.
Providing backup 230V power for plug-in equipment during a supply outage.
Step 1: Place the generator outdoors on firm, level ground, well away from doors, windows and air vents.
Step 2: With the engine off and cool, check the engine oil level and fill the tank with unleaded petrol.
Step 3: Follow the earthing instructions in the manual before connecting any equipment.
Step 4: With nothing plugged in, set the engine switch to ON, turn the fuel tap on and close the choke. Pull the recoil cord sharply until the engine starts, then move the choke to run once the engine is warm.
Step 5: With nothing plugged in, set the voltage selector to 230V or 110V to match your equipment.
Step 6: Check the voltmeter, make sure the AC breakers are on, then plug in the largest load first.
Step 7: Unplug all equipment, switch the engine off, then turn the fuel tap off.
Plugging in before setting the voltage selector to match the equipment.
Expecting full 2700W from the 110V socket, when its 16A rating limits the load.
Running the generator in a cabin, van or other enclosed space.
Forgetting the higher start-up draw of motors when adding up loads.
Refuelling while the engine is running or still hot.
Exhaust gases contain carbon monoxide, so run the generator outdoors only, at least 1m from walls and buildings and away from openings into them. Switch off and let the engine cool before refuelling, and store petrol in approved fuel cans. HSE guidance favours 110V centre-tapped earth supplies for portable tools on construction sites, so check the manual and your site rules before relying on the 110V output. Use an RCD with 230V tools used outdoors. The sound power level is 96dB(A), so wear hearing protection when working close to the generator for long periods.
Check the oil level before every use. Change the oil after the first 8 hours, then every 50 hours, and keep loads under 75% for the first 25 hours. Clean the air filter element in a mild solvent, then lightly oil it before refitting, more often on dusty sites. Inspect leads, plugs and socket covers before each shift. Before long storage, drain the fuel or add a fuel stabiliser, and store the generator in a dry place.
Q: Can this generator run 110V site tools?
A: The yellow 16A socket supplies 110V for standard site tools and leads, so no separate transformer is needed. A selector switch on the panel sets the output to 230V or 110V. The 16A socket rating limits how much load the 110V side can take, so check the 110V figure in the manual for bigger tools. If your site rules require a centre-tapped earth supply, confirm this with the manual before use.
Q: What do 3000W and 2700W mean on a generator?
A: 3000W is the maximum output, which the generator can only hold for short periods, such as while a motor starts. 2700W is the continuous output it can supply for hours at a time. Size your loads against the 2700W figure. The “T3000W” in the model name matches the maximum output.
Q: How long will it run on a full tank?
A: The supplier gives a runtime of about 8 hours from the 15L tank. Actual runtime depends on the load, and lighter loads use less fuel. Keep a filled fuel can on site for full-day work.
Q: What is this generator not suitable for?
A: It is not suitable for indoor or enclosed use, or for loads above 2700W continuous. Do not plan on running 110V and 230V loads together until the manual confirms it, because the panel has a voltage selector. It should not be connected into building wiring unless a qualified electrician fits a changeover switch. The 12V output is for charging batteries only.
Q: Why choose this over a 230V-only petrol generator?
A: It adds a 110V outlet, so standard site tools run without a separate transformer. It also gives 2700W continuous, against 2000W on the 2200W 230V model in the same range. A 230V-only model with UK 3-pin sockets suits work away from construction sites, where 13A plugs are the norm.
Q: Can I plug a standard UK 3-pin plug into this generator?
A: Not directly, because both sockets are 16A industrial sockets. Use a blue 16A to 13A adaptor lead on the 230V socket for equipment with a UK 3-pin plug. Keep the total load within 2700W.
Q: What routine checks does the generator need?
A: Check the oil level before every use, because the low oil shutdown will stop the engine if it runs low. Keep the air filter clean and follow the service intervals in the manual. Inspect leads, plugs and socket covers for damage before each shift.
