You can NOT connect those heaters to a 30 amp circuit.

You CANNOT have 15 or 20A receptacles on a 30A circuit. I can cite the code if you like.
Why would you need them on one circuit?

They appear to be regular 120 volt cord and plug heaters, meant for a 20 amp outlet max. Per code, you can't put a 20 amp outlet on a 30 amp circuit. A 30 amp outlet will not fit the plug on the heaters.

If you need to use two of them from the same outlet, run a MWBC. Otherwise, use 2 different circuits.

These are $20 space heaters from Walmart, according to the model number. They'll have a regular plug on them.

Thank you all very much for your responses. See below for additional clarification.

We are going camping at a state park and the campsite has a 30 amp electrical plugin. I should have not said a 30 amp circuit. To clarify the question "Can you (without tripping the 30 amp breaker box) plug in 2 of these heaters to that 30 amp box?" The box does have a regular outlet to plug anything in to it but i am told it only allows 30 amps of power.

Ugh, campsite electrical. You'll probably (hopefully) find that the campsite electrical box has a 30A trailer receptacle with a 30A breaker, and a standard 15A duplex receptacle on a separate 15A breaker. You can probably run one of those heaters, I wouldn't bet on running two of 'em.

2x1500= 3000watts/120v=25 amps

Thank you all for your replies. I think the final answer is that i should not use this 30 amp hookup for both heaters as this would probably pull more than 80% of the power and this is not recommended for long periods of use.

That is not the reason. The reason is because those heater have 15 amp plugs and are designed to be used on 15 amp circuits.
