Mark,

For PC's you <SHOULD> really run some sort of protection in case of
surges form the genni set.  A UPS will usually do.

Also, to be 100% safe you should multipy the KVA by 0.8 to allow for
power factor correction.

Hope this helps

Stuart

inductive like motors often have Power Correction Capacitors (PF
Correction) installed to make them "appear" to be resistive.
