A single H means the wire is heat resistant.
<<>>
The letter H is also used to designate the primary connection side on a transformer. The letter is usually followed by a number to designate the taps of the primary side. An example is H1 and H2. Dual voltage primaries will have the terminations identifications as H1 and H3, H2 and H4.
