Analysis of GFCI Data
نویسنده
چکیده
This report reanalyzes data from a survey of Ground-Fault Current Interrupters (GFCIs), conducted by the National Electrical Manufacturers Association (NEMA). In that study, participating home inspectors in a number of cities added testing of receptacle and circuit breaker GFCIs to their normal home inspections. The home inspectors reported this data to NEMA. Also as part of the study, homeowners with GFCIs that were found to be non operational were given instructions for free device removal. Removed GFCIs were sent to Underwriters Laboratories. UL conducted further analyses on these GFCIs.

A Hybrid Causal Search Algorithm for Latent Variable Models
Existing score-based causal model search algorithms such as GES (and a speeded up version, FGS) are asymptotically correct, fast, and reliable, but make the unrealistic assumption that the true causal graph does not contain any unmeasured confounders. There are several constraint-based causal search algorithms (e.g RFCI, FCI, or FCI+) that are asymptotically correct without assuming that there ...
متن کاملIsolated Power Systems (IPS) and Wet Locations in
The National Fire Protection Association (NFPA) Standard for Healthcare Facilities (NFPA 99) requires that wet location patient care areas be provided with “special protection against electric shock.” This paper will list the hazards associated with electric shock and the interruption of electrical power. An Isolated Power System (IPS) is one way of providing such protection, and has the inhere...

2) ELECTRICAL SAFETY a) Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock. b) Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if you...
متن کاملWhy Do GFCIs Keep Tripping?
As well known, ground fault circuit interrupters (GFCIs) are used to protect people from electric shock. Recently, a manufacturer installed variable speesd drives (VSDs) in all their products. After receiving feedback from their customers, they realized that their products would only work when powered through some GFCI outlets but not work when powered through others. To investigate this proble...
متن کاملThe Greedy Fast Causal Inference (GFCI) Algorithm for Continuous Variables
GFCIc [Ogarrio, 2016] is an algorithm that takes as input a dataset of continuous variables and outputs a graphical model called a PAG (see the appendix), which is a representation of a set of causal networks that may include hidden confounders. The PAG that GFCIc returns serves as a data-supported hypothesis about causal relationships that exist among the variables in the dataset. Such models ...
