This is an update of the IOTA replacement and installation of the ESCO 50BRD. After installation I didn't have 120 Vac on one leg using generator power (8Kw). I probed all connections relating to the area of concern and while probing connections I manually exercised the suspect relay several times. This manual actuation of the relay provided the electrical connections needed as operations of both power systems (line and generator) are now operating as designed. Per telecom with Tom Cherry, who is extremely knowledgeable and helpful, the problem and solution was discussed with ESCO engineering. ESCO and Tom Cherry both advised repeated operation and testing or send unit back if desired. It appears there was a misalignment of contacts either during shipment or installation. I have since tested the unit extensively (vibration, etc.) and will monitor as needed. The anomaly appears to been corrected so I am keeping the unit as opposed to sending it back. I would like to thank you all for your inputs and especially Tom Cherry and ESCO engineering for their support. Thank you ... Jim 2007 Diplomat 36PDQ

Walker, thank you and others for responding .... The last sentence of the "GENERATOR POWER TO COACH" paragraph "A" says "for 120vac generator input, HOT ONE should be jumper to HOT TWO" ??? I did connect all inputs to the new transfer switch according to the diagram on the panel. Was a little difficult as all in puts were reversed from that in the IOTA. Every thing works ... except the input to distribution panel of house (input "7") does not have 120vac with the generator. The generator is providing 120 vac to input "4" on the panel. Hope that helps... Thanks, Jim

I just replaced my IOTA transfer switch today with the recommended ESCO 50BRD, but didn't add the jumper wire between the HOT 1 and HOT 2 for the generator input. This is on a 2007 Diplomat 36PDQ with an 8kw Onan generator (original owner). I was a bit nervous about adding a jumper between the two HOT wire inputs. It's probably the correct thing to do as it is specified in the trouble shooting guide to add this jumper. I just need to hear it from you folks that it's OK. Upon testing without the "jumper" on generator input, there was a lack of power on LINE 1. Line 2 had the required 120v. Shore power was fine as was the generator "delay" and associated LED illuminated. I just need assurance from you folks that have done this and it's OK before I fry an electrical system that has been great so far. Thank you for any info .... as we have loved this motor home. Didn't see the jumper on the IOTA transfer switch .... Jim S. Coeur d'Alene, Idaho
