Exempts licensed master plumbers from certain electrical contractor business permit requirements.

S 1437 exempts licensed master plumbers in New Jersey from needing an electrical contractor business permit when performing specific tasks: replacing electric water heaters (similar size/voltage ≤240 volts) and replacing air conditioning condensing units. This change directly affects licensed master plumbers who install or maintain these common household appliances. The bill amends existing law to remove permit requirements for these routine maintenance activities, streamlining work for plumbers who already handle related electrical components. It applies to contracts initiated after the bill's effective date.
