| Mar 9, 2021 at 14:06 | comment | added | user2285215 | yes @jay613 you are correct, thermostat wire comes from right side of the box, which is a (conduit?) going up to the ceiling > lightbulb/socket > wall. Is the safety issue pertaining to me "adding a C-wire" or just how its currently wired? heh | |
| Mar 9, 2021 at 10:28 | comment | added | jay613 | Just to reopen this can of copper worms, I think the thermostat wire enters through the EMT on the top right side of the cutoff box, the same EMT as the power source. I think the green is already connected to neutral! Ironic. But this doesn't change the outcome ... It should be redone by an electrician as there are serious safety issues here. | |

| Mar 9, 2021 at 3:35 | comment | added | user2285215 | Thanks for your reply. Ive added a couple of photos of the thermostat wires. Based on your input I suspect that this is something more than I can handle. I was hoping to avoid plugging in a 24VAC transformer | |
| Mar 9, 2021 at 3:27 | comment | added | jay613 | Given the way the low voltage wires fold back into the junction box, I don't think we know for sure how the pressuretrol is wired but I agree with the advice, this boiler deserves a look by someone knowledgeable. | |
