RV Electrical Panel

Im running an rv panel 300ft with a 30 amp and 50 amp plugs. The 30 amp will be for an rv and the 50 amp will be for a 40 amp electric car charger. Wondering if #2 aluminum wire would be big enough to carry this also what size breaker to use? And do I need a grounding rod at the rv panel?

#2 aluminum i good for at least 90A. 90A-100A breaker.
Your RV panel is considered a sub panel so you will need four wires. Two hots, neutral and ground.
The neutral and ground must remain separate.
Yes.... you will need a ground rod there connected to the ground wire only.

Proper Panel Ground?

G

Gen on Nov 22, 2019

At a particular property we have primary breaker panel. ( It's a really a sub panel because Ground & neutral are not joined and a single main cut-off panel is 35 feet away outside the house.) Anyway we have 4 SE wires coming in from there...the 2 hots, and the white wire to the neutral bus. Then bare aluminum wire, spun around the other 3 wires, which goes to a lug that is bolted to the panel case. Additionally have 2 ground bus strips are screwed onto the case as well, all ground wires are there. Lastly, and to my question, we have the #6 bare copper coming in from ground rods, then to the single breaker cut-off panel, then into house....but it does not terminate at the sub-panel ground bus, only to the incoming cold water pipe. Is this proper? Should it at least go to ground bus? Part of the reason I ask is that the house, despite surge protectors, has incurred a lot of surge damage. And I am aware surge devices are dependent on good grounding. Thanks!Read More

Updating ceiling light fixture with knob and tube wiring

M

mariannap on Nov 25, 2019

Hello everyone, I'm trying to update a light fixture in my 1929 house. The walls are made of plaster and lathe, and some of the ceiling lights still have knob and tube wiring. I want to install a new light fixture, but am unsure how to do so with the knob and tube. I've read a few things online that say legally I need to install a new electrical box, but I don't know how to do that with the current setup of the light. Does anyone have any suggestions? Photos can be found in the links below. Any help is greatly appreciated!! [attach]111245[/attach] [attach]111246[/attach] [attach]111247[/attach]Read More
