Ouellet OCC4800AM-MO-TB6 Portable Construction Heater 4800W 240/208V

The Ouellet OCC4800AM-MO-TB6 is a portable construction heater rated 4800 / 3600 W at 240 / 208 V, finished in almond. Put simply, it is a 4800 W portable construction heater on a roll cage - temporary heat for a site that has power but no permanent heating system yet, and no tolerance for open flame.

TL;DR

• Output: 4800 / 3600 W at 240 / 208 V (16,390 / 12,290 BTU/h)
• Draw: about 20.0 A - size the circuit at 125% per CEC 8-104
• Finish: Almond
• Control: not included - needs a line-voltage thermostat
• Availability: in stock in Vaughan, ON. Ships Canada-wide, counter pickup available

Quick Specs

Best For

• Construction sites needing temporary heat through an Ontario winter
• Concrete curing and drywall mudding in unheated buildings
• Renovations where the permanent system is offline
• Contractors tired of renting the same heater every winter

Why Contractors Choose It

• 4800 W of electric heat with no fuel, no fumes, no CO monitoring and no refuelling trips
• Roll cage and carry handle survive real site handling
• Buy once instead of renting through five months of winter
• Safe to run in enclosed spaces where a combustion heater is not

Installation Notes

Portable construction heaters are cord-and-plug connected. Match the plug configuration to the site receptacle, protect the branch circuit per CEC Section 62 and 8-104, and keep the nameplate clearance to tarps, lumber and any combustible material on site.

Common Mistakes to Avoid

• Plugging into a circuit that cannot carry 4800 W
• Running it against tarps or stacked lumber without the nameplate clearance
• Taking the fan model when the job needs the motor-only unit, or the reverse

Frequently Asked Questions

Is the Ouellet OCC4800AM-MO-TB6 CSA certified for use in Canada?
Ouellet is a Quebec manufacturer and its heating products are built to Canadian standards and certified for the Canadian market. Confirm the certification mark and the ratings on the unit's own nameplate against your local amendments before you energize it.

Where does Maple Electric Supply ship this from?
From our own stock in Vaughan, Ontario. That means no cross-border wait, no duty and no surprise brokerage on a heater you need before the cold hits. Counter pickup is available, and we ship across Canada.

What does the 4800 / 3600 W rating on the OCC4800AM-MO-TB6 actually mean?
This unit is dual-rated. On a 240 V supply it delivers 4800 W. Put the same unit on a 208 V supply and output drops to about 3600 W - roughly 75%, because output falls with the square of the voltage. Order on the voltage the building actually has, not the one on the drawing.

What size breaker and wire does the OCC4800AM-MO-TB6 need?
The unit draws about 20.0 A at 240 V. Fixed electric heat is a continuous load, so CEC 8-104 sizes the conductor and the breaker at 125% of that - about 25.0 A. Your electrician sizes the final circuit against everything else on it; a 15 A 240 V circuit tops out at 2880 W of total connected heat.

How much heat is 4800 W in a real room?
16,390 / 12,290 BTU/h. As a working rule of thumb for an insulated Ontario room, budget roughly 10 W per square foot for a well-insulated space and closer to 15 W per square foot for a basement, a room over a garage or anything with a lot of glass. Send us the dimensions and we will size it properly.

Does the OCC4800AM-MO-TB6 include a thermostat?
No - this is the base unit and it needs a control. You can either run a line-voltage wall thermostat, or order the equivalent part number with a factory-installed thermostat built in. We stock both, plus the Ouellet stats that suit them.

Can I run this in an enclosed space?
Yes - that is the point of electric temporary heat. There is no combustion, so no carbon monoxide, no fumes and no combustion-air requirement. Keep the nameplate clearance to tarps, lumber and anything else combustible on the site.

Is buying cheaper than renting for a winter?
Usually. Five months of rental on a jobsite heater will typically exceed the purchase price, and then you own it for the next winter. If you run more than one site, that gap widens fast.

Can I get a price on a full job's worth?
Yes. Multi-unit and contractor pricing is available on Ouellet heating - send the schedule or the count and we will quote it. Most heating orders over a handful of units are priced by our counter team rather than at list.
