All circuits are identical.

All loads are identical.
Never got the hang of pictures. Can you do as in terms of i please? Or j if you're an engineer.
Here with i and j.
i_k(t) = sin(100·t·π + 2/3·π·k) = (e^j(100·t·π + 2/3·π·k) - e^-j(100·t·π + 2/3·π·k))/2j
i_n(t) = i_0(t) + i_1(t) + i_3(t)
The rest is trivial.
From my experience using a portable heater ...only advice is ...if extension cord is getting hot then it is not rated high enough and may be fire hazard before trips/fuses triggered. (It should be printed on the cable or on a tag. ).
Picture this:
P1 is at 0 degrees, so has no "i" component, which leaves you with 1.
P2 and P3 are equal but with opposite "i" components, so they cancel and leave you with -0.5 + -0.5 = -1, as the real part is cos(120) = cos(240) = -0.5
1 + -1 = 0;

3500W for a portable induction oven !!!!
it's a lot.
Do you have a link to the specs?
Tom
Thats the one I have:
It is 3500W
The electrical outlet must be protected by a 16A safety cut-out switch.
The connection between the device and the electrical network may employ a 3 meter long (max.) extension cable with a cross-section of 1.5 mm2. The use of multiple plugs or gangs is prohibited because of the danger of fire that is involved with this.
