This is a difficult question because it seems that, although the landlord is putting a heavy load on a single circuit, the landlord is also paying for the electricity. At least that's how I read your sentence that electricity was included. If that is correct, you are not being billed for his use of the power. So I don't believe that if the landlord is paying for the electricity, and if this air conditioner was for your own use, that he is obligated to use less electricity so as not to trip your current A/C. You might try and talk with the landlord about the situation to see if you can work something out, but from what you write, I don't think the landlord is denying you your rights. Again, if you are paying your electric, and he is using your power, then my answer would be different.
