How to get PEA to upgrade my Amp Service

Recommended Posts

If i fire up the welder then what ever circuit it is connected to is going to pop, just normal operations, if the wife turns on the oven and its starts pulling juice it gets dark.  If my compressor is cycling on and off, i typically get the dimming efffect.

Well, that was a photo with the cover on but it will suffice for now.  What is connected to the 32 amp circuits?  No wonder you are popping the other breakers as they are only 10 amp.  If your wire size to receptacles is 2.5mm² you can change breaker size to 20 amp and probably solve that issue.

I don't have a clue, when I had the house built they didn't label anything.  OK i will check the wires to see what size they are tomorrow morning when the kids leave for school.  They are all home today, if i kill power to open the box they will start a revolution due to the playstation not being available.

Could be higher than it should because your meter is calibrated to 5 amps and you can guess which way the distortion will go if higher.

 

As to the dimming when you turn on a high load... that could indicate that your PEA supply needs a boost.  It will help your case if you can provide voltage measurement at your CU AND your meter before/during the high load.

You can open the box (take the cover off) without worry - just don't go poking around inside with power on.  It will be good to know the wire sizes to which breaker.  Turning off a breaker will tell you what is connected to it because <whatever that is> won't turn on.

Also to note that you do not have RCD protection (you should) and after you remove the cover check on the ground/earth situation.  IE: do you have a large wire from earth bar going out to a ground rod?  How many wires are connected to the earth bus?  Or take a photo maybe with a bit more resolution if you can.

I am not a photographer, but hope it gives you a better idea.  The wires are not thin by any means.

Actually you did good with the photos but your camera won't win any awards.  All the circuit wires look the same size to me - which means the 32 amp circuits are not properly sized.

 

So that's the earth bar at the top and the neutral bar on the left, yah?  That large wire on the earth bar is hopefully going to the ground rod.  There's at least 4 other wires connected to the earth bar?  That indicates that your ground situation should be OK.

What is the solution, larger breakers?

With the 32 amp breaker being the main incoming side, will i need to kill power at the pole to change them?

That's a 5/15 (max 15A) service, no wonder you're running out of power 🙂

 

You should be able to get an upgrade to a 15/45 (max 45A) without much trouble. You may need to upgrade the wires from the meter to your house, it depends what size they are now, and you'll need a 45/50A main breaker in the house.

 

Take yourself along to your local PEA office, take your latest bill and a Thai speaker. You will need to pay a deposit on the new meter (you should get a refund on the old meter), their man should be able to tell you what needs doing (they may or may not do a survey).

 

That was not the case for us, despite Mrs BM arranging for the supply to our whole road to be renewed and re-routed a couple of years ago (after we had waited for a year), we have been unable to get them to sell us more than 15 amps. This is a real PITA with no resolution in sight.

Is that a 5/15 or 15/45 you cannot upgrade?

 

Many places cannot go above a 15/45.

First determine what is on those (32a) circuits.  Solution is 20a breakers OR 4-6mm² wires.  Do you have an outbuilding for your welder?  What does that need for power?

Crossy if PEA asks me should i max out at 15/45 or just do incremental upgrading.
