Converting a Low Volt Lighting System

How to Identify and Convert Low Voltage Light Switches

Identifying Low Voltage Switching and Light Fixtures

Electrical Question: I have a 1970 house. I bought some new wall sconces that run on line voltage, in order to replace some recessed lighting . I discovered that the current lighting runs on low voltage (12v) by examining the bulbs and discovering there is a step-down transformer on the circuit. The transformer is close to the electrical panel and drops the voltage before it gets to the switch that controls the current lights. However, the wiring in the junction box for the sconces appears to be the same 60nm Romex with standard 14-gauge wiring as what comes out of the electrical panel on that circuit. If I just remove the transformer, will everything work fine? I’m a little concerned that there may be some low voltage wiring somewhere behind the walls on that circuit that I can’t see even though both ends look to be standard 14 gauge wiring. I can’t see any markings on the wiring to read the gauge.
