...at the same time,
please explain, my books answer just says--yes, as less than 27amps is drawn, Im so confused
thank you

The ring circuit acts like two radial circuits proceeding in opposite directions around the ring, the dividing point between them dependent on the distribution of load in the ring. If the load is evenly split across the two directions, the current in each direction is half of the total, allowing the use of wire with half the current-carrying capacity. In practice, the load does not always split evenly, so thicker wire is used.
Your question was posted from a server in the USA. Assuming that you live there then your domestic supply is 120 V at 60Hz, if my memory serves. Recall that
Watts = Volts * amps.
1kW = 1000 W = 120 * A
A = 1000/ 120 = 8.33 A
Assuming that the split point is in the middle, this currect will be divided by 2 to give
4.15 A per fire. Six fires would need 6 * 4.15 = 24.9 A, so the 30 A cable is safe.
