The voltage between conductors of two different grounded sources like this depends on which phase of each supply each conductor is on. You can actually change this difference by swapping phases on either or both circuits."Circuits of different voltages can be run in the same raceways or occupy the same .
"Circuits of different voltages can be run in the same raceways or occupy the same spaces (enclosures, equipment) providing that the voltage is less than 600 volts and the . You can SPLICE wires in the box, as long as the insulation on all the conductors is suitable for the to the highest voltage in the box. Since most wire used has a 600volt rating, if . High and low voltage conductors in the same junction box must be separated by a barrier. Outdated NEC reference: 800-52(a)(1)c.1.Exception 1. In the typical dbl. gang box . You couldn’t mix line voltage and low voltage (e.g. 12 volts) in the same box. You can interconnect the grounds or not. If the box is metal and the conduit is not (or no conduit), .
It's not at all abnormal or uncommon to have multiple circuits from different sources (different panels, different voltages, even different services altogether) in the same .
Safety is also a factor with different voltages all in the same junction box. I have to agree with the Canadian Electrical Code, its not allowed except for the supply and control of .

"Circuits of different voltages can be run in the same raceways or occupy the same spaces (enclosures, equipment) providing that the voltage is less than 600 volts and the conductors each have insulation ratings greater than or equal to .

Since most wire used has a 600volt rating, if you have a J-box with 120 and 277/480 being spiced and then run to where ever, your good to go.
High and low voltage conductors in the same junction box must be separated by a barrier. Outdated NEC reference: 800-52(a)(1)c.1.Exception 1. In the typical dbl. gang box installation, power in one half and phone and data in the other, there needs to be a partition in the box separating the two classes of conductors. You couldn’t mix line voltage and low voltage (e.g. 12 volts) in the same box. You can interconnect the grounds or not. If the box is metal and the conduit is not (or no conduit), you’ll need to tie one or both grounds to the box. Be careful not .
It's not at all abnormal or uncommon to have multiple circuits from different sources (different panels, different voltages, even different services altogether) in the same junction box. Simply keep their neutrals separate, and tie all the grounding wires together.
Safety is also a factor with different voltages all in the same junction box. I have to agree with the Canadian Electrical Code, its not allowed except for the supply and control of remote devices, like a motor starter, if all conductors are insulated for the highest voltage. One of the biggest no-nos is wiring multiple circuits together in one junction box, if they have different voltages. It’s like trying to mix oil and water – they just don’t play well together. Think of it this way: each circuit is like a unique personality, with its own quirks and preferences.
What is your interpretation of the code pertaining to different voltages in the same conduit? There is none, your free to mix voltages. There are restrictions on mixing certain systems or classes together. All the conductors must be insulated for the highest voltage. And only for conductors of electric power, light and similar. It is legal as long as the conductors are rated for the same voltage and the neutrals are identified separately. Can you mix voltages in a junction box? Q. Can a junction box contain both 277V and 120V conductors? A. Yes, providing all conductors have an insulation voltage rating not less than the maximum circuit voltage (277V) [300.3 (C)].
