Paul Keleher

Welcome to Paul Keleher Electrical Services

Based in Berlin, Massachusetts with a Master Electrician's license since 1986, Paul Keleher has been actively promoting a "green" use of electricity for home heating using OFF-PEAK electricity, and in keeping older homes and their wiring safe from electrical fire. To this end, Paul Keleher has developed his unique expertise in several areas:

  • Paul has developed methods to test and treat older wiring systems to greatly improve their fire safety without going to the often prohibitive expense of rewiring, and at a fraction of the cost.

  • In evaluating the safety of a home's wiring, Paul realized long ago that no effective method to test an installed circuit breaker has existed, and that since the circuit breaker is a home's only protection from an electrical fire if a problem develops, a need existed to test installed circuit breakers quickly, safely and economically.

Paul has obtained 3 US patents protecting safe methods of testing installed circuit breakers quickly, safely and economically without tools. A beta product has been developed and sold in limited quantity that conducts an effective test of the short-circuit response of any installed 120V circuit breaker, and stores its results for later analysis.

Analysis of some of these tests indicate that due largely to a lack of effective coordination between the circuit breaker product standards and the National Electrical Code, which regulates the installation of electrical distribution systems and equipment in homes and buildings, the circuit breakers protecting 120V branch circuits do not perform as intended when responding to short-circuits or ground-faults, leaving circuits vulnerable to safety hazards. To address this apparent deficiency, Paul has proposed changes to the National Electrical Code that will ensure that circuit breakers perform as designed.
