Over 10 years ago I had a Load Master IIB by Pensar installed in my home to maintain my peak demand for electricity. Recently it started shutting things down even when the demand was set at 15. I assume that it just got old and tired, so I shut off the breaker to the Load Master. Does anyone make a reasonably priced replacement unit. It has the digital control unit mounted inside as well as the box outside near the main electric panel. I assume that just the inside component is bad.

You might give Electrosem in Tempe a call if they are still in business. Sounds like there may be a change of equipment in your house that may need new demand loading for the peak usage settings. Nm
