SIZE RECOMMENDATIONS.

WARNING

Only a licensed, certified, trained electrician should install the machine to a premises or residential electrical system. Be certain that:

•The installation complies with the National Electrical Code and all other applicable electrical codes.

•The premises is isolated and no feedback into the utility system can occur. Certain state and local laws require the premises to be isolated before the generator is linked to the premises. Check your state and local requirements.

•A double pole, double throw transfer switch in conjunction with the properly rated double throw cir cuit breaker is connected between the generator power and the utility meter.
