1. A method of inserting a downhole assembly into a live wellbore, comprising:
- assembling a pressure control assembly (PCA) onto a production tree of the live wellbore;
inserting a first deployment section of the downhole assembly into a lubricator;
landing the lubricator onto the PCA;
connecting the lubricator to the PCA;
lowering the first deployment section into the PCA;
engaging a clamp of the PCA with the first deployment section;
after engaging the clamp, isolating an upper portion of the PCA from a lower portion of the PCA; and
after isolating the PCA, removing the lubricator from the PCA.

12. A pressure control assembly for inserting a downhole assembly into a live wellbore, comprising:
-
a first clamp comprising a housing having a bore therethrough and bands or slips, each band or slip radially movable relative to the first clamp housing into and from the first clamp bore; a second clamp comprising a housing having a bore therethrough and bands or slips, each second band or slip radially movable relative to the second clamp housing into and from the second clamp bore; a preventer or packer comprising a housing having a bore therethrough, a seal, and an actuator operable to extend and retract the seal into and from the preventer or packer housing bore; an isolation valve comprising a housing having a bore therethrough and a valve member operable to open and close the valve bore; and a driver comprising a housing having a bore therethrough and a wrench radially movable relative to the housing into and from the driver bore, the wrench comprising a motor and a socket, the socket operable to engage a threaded fastener and the motor operable to rotate the socket, wherein the clamp housings, the preventer or packer housing, the valve housing, and the driver housing are connected to form a continuous bore through the assembly.
