8. es not matter which is hot 1 and which is hot 2 H In some applications it may be desirable to feed a 120 volt supply such as an inverter into both hot legs of a transfer switch so that the 120 volt supply can operate the entire RV load Although discretion is advised in designing this into the system it is acceptable as long as the connection to both hot legs is accomplished on the input side of the transfer switch To do this connect the hot from the 120 volt supply such as an inverter to hot 1 and then attach a jumper wire of the same gauge from hot 1 to hot 2 Consideration should be given to the following The entire load must be 120 volt you cannot operate 240 volt load from a 120 volt supply There may be a load which would be undesirable to run from this particular 120 volt supply that load should be isolated when the 120 volt supply is operating The TS 50 is sometimes used as a lock out switch to prevent specific loads from being operated from designated supplies Example preventing a battery charger or air conditioner from running from an inverter yet operating from generator or powercord Tighten cable clamps on switch enclosure J Attach lid The lid is designed to snap on and should not open without deliberate effort 2 5 1 Installation Between Powercord and Generator Configuration A The TS 50 is designed with an easy to wire bridge Refer to Diagram 1 for wiring lug designations 1 Conn
