Junction Box Sizing Examples. Understanding junction box sizing through practical examples offers clarity: For a 4×4 Box: Consider a standard 4×4 junction box. When using 14/2 wires, this box can accommodate approximately 7 wires. Yes fine in my view, to require that 5 amp junction boxes be replaced when a 5 amp fuse is replaced with a 6 amp MCB is IMHO over pedantic. The load probably wont exceed 5 amps, and with the general use of low energy lamps is unlikely to exceed even half that.
We have many VAV boxes on a floor of a new building. Each box has controls that add up to 20 VA. Each box has a 40VA transformer, 120v to 24v. How do I calculate how many VAV boxes can go on a 20 amp 120 volt circuit?Yeahhh, we work on 1900s houses all the time. It's simply the fact that SO many people and contractors have been through repurposing and fixing things. Are you going to say you never found a bad splice.Maybe you havn't done many service calls.
