Lighting question

[lovemytoys]

ok 4 lights at about 1.6 amps=6.4 amps and a small refrigerator is about 4maybe 5 amps=11.4 amps at 110 volts .but when you have voltage loss your amps go up .then added the small power surge when the compressor comes on .now you are pushing it.

Good, I understand perfectly.
?Question, why are you including the refrigerator in the calculation? it is already wired, it will not be on the new line it it will not have much of any effect.
and the lights at 6 amps will not have much effect on the frige because it is up stream.
If amps=watts / volts , 175 /120=1.46 amps not to split hairs. and again if he uses HPS it will only be 400w and thats a no brainer.
If your still worried then, when you do it, use what ever you want.

When you have voltage loss on lamps the amps goes down. The only time the amps goes up is when you keep doing the same work when you have voltage loss.....Larry

it all count it total load .the ref is going to be on the same feed .If amps=watts / volts , 175 /120=1.46 amps not to split hairs,that not with the voltage drop!i been doing this for enough years to know

ok let see votage drop .now you have 98 volts x4-175 watt bulbs now we are at 1.78 amps

 

[mopacman]

when voltage drops the wattage goes down. The only time a bulb uses its rated wattage is when it is at rated voltage......Larry

 

[ray66v]

Yes, the frig, does count for total load on the front at the breaker but the voltge drop is at the end of the curcuit. It is going to drop after the frig. So, don't see it adding to the drop

but the amps goes up

Hate to burst any bubbles here.. but at least for incandescent lamps.. we are looking at a fixed resistance that becomes stable when the filament is hot... that's the 1 fixed variable of ohms law you can then plug the rest in and play.... use a fixed 'r' and plug in different values of 'e'

Remember.. wattage is not constant... a 12v car battery and a house outlet don't make a 100w 120v bulb glow the same... by some of the logic I've seen thrown around here... they would glow the same.. but the car battery would be sourcing some big amperage....... which.. in practice... it won't.... due to the resistance of the filament.. once it settles down..

I'm by no means an expert, but I would agree with lovemytoys. With a panel out at the arena you can run your lights and if you need something else once in awhile you have the extra to do it. I'm not sure what the cost difference would be though.
