Or did you completely wire your basement with dozens of wires dangling where the sub panel would go and then have the professional install the sub panel, and wire and install the breakers? Good question - I had a professional install the sub-panel and hook up the 5 or 6 circuits that I had already run.
However, when I added my bathroom GFI a month or so later - I was able to turn of the power to the sub-panel and then fairly easily install my own circuit breaker and wire it up. I do not recommend installing your own sub-panel. I'd be very careful. Most jurisdictions are not going to give you a final without the power turned on. Splices and torque are key.

Wires within the sheathing are insulated with color-coded PVC polyvinyl chloride. The individual conductors normally have black, white, and red insulation. Also present within the NM cable is a copper grounding wire that is usually left uncoated and bare but sometimes is coated in green PVC.
Often, paper will be added within the cable as a separator. This paper can be snipped and discarded in the ripped portion of the cable. To connect to devices, wire insulation is stripped from the copper wire with a manual wire stripper. A series of holes in the wire stripper correlates with different wire diameters, or gauges. For example, choose the hole labeled "12" to strip the insulation from gauge wire. Despite the NM label, the individual electrical conductors within the cable are indeed metal—normally about percent copper.
NM cable comes in many wire gauges, but most household circuits will use gauge or gauge wire, with either two or three conductors inside plus the bare copper ground wire. For example, a cable labeled " with ground" will have two insulated conductors with gauge wires plus a bare copper grounding wire. This cable is used for amp circuits and often powers circuits from panels and individual devices.
A cable labeled " with ground" will have three gauge insulated conductors white, black, and red plus the bare copper grounding wire.
A gauge cable is rated for amp circuits. Southwire notes that they "vigorously monitor and protect the use of the Romex brand. Within the world of building products, the word Romex is often used in the same way that Kleenex is used to refer to any tissue: generically and erroneously.

It may mean that the wire at the time was experimental or it may have simply been a convenient method of creating a brand name.
