Claim 17:
18. An electrosurgical system for delivering energy to tissue comprising:
a generator having a maximum output and at least two channels;
at least two electrosurgical probes operable to be connected to the at least two channels such that the at least two channels are configured to deliver energy; and
a control system, when the at least two electrosurgical probes are connected to the at least two channels, being configured to:
(a) activate at least one channel of the at least two channels which are to be activated;
(b) check for disabling conditions, where disabling conditions include to check if at least one channel of the at least two channels to be activated is in a ramping phase and to check if at least one channel of the at least two channels has been disabled;
(c) in response to disabling conditions, disable at least one channel, of the at least two channels, from amongst all active channels based on whether at least one channel to be activated is in a ramping phase or at least one channel is disable; and

wherein the control system is configured to check if total power used by all active channels is less than (Ptotal×safety factor YY×Plast for system waiting time enabling) wherein time T is a time at which a most recently disabled and not currently enabled channel was shut off, and wherein Ptotal is a total requested power across all channels at time T, and wherein Plast is a last output power of the most recent channel disabled and not currently enabled at time T, and wherein system waiting timeenabling is a period of time the system waits after any status changes before enabling another channel.
