There's no need or purpose in removing any insulation. A clamp around Amp-meter will measure the current with insulation intact. It's measuring the EMF.
As further clarification, the typical clamp around amperage measuring meter - here's a photo of an Amp-Probe model, has a set of jaws that open to allow you to wrap the jaws around an insulated conductor, the jaws then close to create a loop around the conductor. There's usually a few inches of clearance between the conductors and the insulated jaws of the meter. Care and attention needs to be in place to do this measuring safely and Steve T. has listed a link as to the methods now required.
As to usage. One typical example would be attempting to get a rough measurement of the normal load on an electrical panel that has space(s) for additional breakers, but whose existing loading is undetermined. Removing the panel cover and testing the hot legs, presumably while the loading is as close to maximum current usage, would then yield a reading.
