does it work without a ground? null

Yes but your defeating the purpose of a good surge protector. To work optimum you need a ground...I do have an old house and only a few outlets don't have an actual ground hook up.. but it still works.

Thank you for reaching out. Our surge protectors and UPS units all require connection to a grounded outlet. Our units have a site wiring fault led which will come on if one of the 3 following conditions exists: The Site Wiring Fault (SWF) LED light is only present on 120V UPS and Surge products. On APC UPS products this indicator is typically on the rear panel. The purpose of this indicator light is to warn you that there are problems with your building wiring that may result in a shock hazard. APC recommends that you have a qualified electrician inspect your wiring for one or more of the conditions listed below. Reasons why the Site Wiring Fault (SWF) LED light will illuminate: Overloaded neutral wire (>5 Volts AC measured between Neutral and Ground). Reversed polarity (hot and neutral wires are reversed). Missing ground wire. (Note: this also includes using a 3 prong to 2 prong adapter)
