Outlets for a Tennis Court
 

I am working on a tennis court where the owner wants to add outlets at each of the eight lights to supply as much power as possible for when they use the court for functions other than tennis. They also want the lights off when they are using the outlets.

The court has eight lights divided into two 30 amp 240 volt circuits. The lights are turned on by a single switch that controls a relay with four sets of contacts. The power runs from the panel and the 30 amp breakers to the relay and then splits off to the two end poles on each side. From there wire is run in conduit to the other three poles on each side(one circuit breaker covers one side of the court and the second breaker for the other side).

I know that I can not put an outlet on one leg of the breaker so I think I need to add a sub panel at the first pole with a 20 amp breaker. This would connect to one leg of the 240V 30 A circuit. And do this for each leg of the two 30 amp breakers. There will also be a switch at each pole to disconnect power to the lights.

So:

1) Will this work and be legal?
2) Could I have two 20 amp breakers for each 30 amp leg?
3) What type of panel could I use that would be exposed to the elements?

Thanks for taking the time to read this post.

If you don't know these answers, why are you doing electrical work for someone else?

Have the owner call an electrician.

People just don't understand the concept of DIY means at your OWN residence.


My question is, is there no thought process of the consequences if someone gets injured or killed?

+1 !!!!

There is much more to this than you think. 240volt lights means you do not have a neutral for the 120. You need to pull more wires. Might as well pull a proper circuit for the receptacles separate from the lights.

Thanks for the reply's, the owner is my brother and he is helping me out.

joed,

I thought there was a neutral because someone previously added outlets to each pole connecting to one leg of the 240. I just checked and they just used the ground for a neutral.

The part I wrote the underline which this is very dangerous to do that.

I rather just run proper netural if you going to use the receptales ( this part it much wiser have electrican to assit you on that )

The other issue is that I know some tennis court they will direct bury the UF cable and will be very diffucutally to replace if you have this in conduit it may be a doable depending on the condtion of exsting conduits.

Otherwise you will have to bury a seperated conduit if the oringal one is too small to add a proper circuit.

Oh that's wonderful. I guess they did not like many of their guests. Maybe they wanted to kill them off one by one. :whistling2:

Thanks alot Pete ! :censored: ( French cussing ) I have to clean my keyboard I own ya one :thumbsup:

Merci,

Thanks for the info, a neutral will be pulled if it can, if not then we quit. How high above the ground does the subpanel need to be and is a grounding rod required?
