A 120 volt electrical system will:

A 120 volt electrical system will:

• A. Not require a GFCI circuit if installed near a poll
• B. Not provide enough electricity to light all trees
• C. Require a licensed electrician to provide 115 to 120 volt circuit where the transformer is located
• D. Be inadequate for low voltage systems

Answer: (C)

The main idea here is that line-voltage wiring needs to be installed by a licensed electrician to meet safety standards and electrical code, especially when feeding a transformer that will supply low-voltage irrigation components. A 120-volt circuit powers the transformer’s input, and getting that circuit right—including proper wiring, overcurrent protection, grounding, and weatherproofing—requires a licensed professional and often a permit. That’s why the statement about needing a licensed electrician to provide a 115 to 120 volt circuit where the transformer is located is the best answer. GFCI requirements can apply to outdoor receptacles, but whether a GFCI is required isn’t the defining point of this scenario. The idea that a 120 V system cannot light trees or cannot support low-voltage setups isn’t correct; the transformer can convert that 120 V to the low voltage used by irrigation valves and lights, so a properly installed 120 V supply is compatible with low-voltage needs.
