If you have a 200 amp service you need the 200 amp transfer switch for the utility connection. If you compute the load maximum load on the residence accrding to NEC 220, the generator only has to supply that amount; perhaps ?120 amps? That is still a LARGE generator. If the transfer switch can contol some of the load, perhaps shutting down the electric heat or water heater or etc, then the generator must only be suzed for the remaining load. <br>A manual transfer swich can have a plackard that says: TURN OFF HEAT, RANGE, WATER, HEATER, DRYER BEFORE CONNECTING GENERATOR.<br>The automatic switch can connect anythingthat is on the load side. The generator must be able to carry all the load connected, or have provisions to shed some of the load</p>inspector32513Wed, 21 Oct 2009 15:45:39 -0000http://ecmweb.com/nec/code_qa/code_qa_050709/#comment-9186806<p>i ALWAYS use a full 10' stick of pipe on each end. After the pumps are set, it is often necessary to 'tweak' the alignment of the conduit. Having a full 10' supported reduces the chance the conduit will be broken at the intersection with the PVC.</p>inspector32513Sun, 10 May 2009 15:26:33 -0000
