I think your issue is the earth ground no neutral. You should run that to a neutral wire. All my 220V ACs can do a neutral (white) and 2 power (black) wires, but they aren't connected to a ground wire...

I have 110 volts n each leg but not 220 across both why??


In a traditional North American residential electrical panel (120/240 volt, single phase), installing a single width or single pole circuit breaker, you would expect to read 120 volts from the breaker terminal screw to either ground or neutral. A double width or double pole breaker would provide 120 volts from either of the breaker terminal screws to ground or neutral AND it will provide 240 volts BETWEEN the TWO breaker terminals.

A single-width circuit breaker case that contains two handles is NOT a two pole circuit breaker (these are called "tandem" or "1/2 size" breakers). This is because a single width breaker engages only one "line" in the panel. A double width breaker will engage 2 "lines" as a triple width breaker would engage 3 "lines" of a 3 phase panel. A single wide breaker can not physically engage more than 1 "line" so it will never be able to pass 240 volts.

You must install a double width / double pole breaker to safely supply a 240 volt circuit / device.

Can I change out a Hayward H400ID with an electric heater for the spa only? If so what electric heater product brand would you recommned. Raypak?


Hayward has manuals for each type heater, gas and electric.
http://www.hayward-pool.com/prd/In-Ground-Pool-Manuals_10201_10551_14502_-1___I.htm
Hayward also has contact page, and can probably recommend correct change-over product.

You want to switch from propane to heat-pump type.

There are likely 3 areas of difference. Read each manual and generally look for 1) unit size and capability to match spa 2) pipe connections and sizes 3) Electrical requirement

From electrical standpoint, You need GFCI-protected line from circuit breaker box, or GFCI (arc-fault) breaker. This will prevent electrocution risk around spa.
http://waterheatertimer.org/How-to-wire-GFCI.html

Wire sizes are based on volts and watt-rating of heater.
Each electrical device has rating plate showing volts and watts.
3500 watts divided by 240 volts = 14.5 amps so install double-pole 20 amp breaker and use 12 gauge wire.
1500 watts divided by 120 volts = 12.5 amps so install sinle-pole 20 amp breaker and 12 gauge wire.

What cable is needed to supply a 9.5kw elecric shower


9500 watts is a lot of watts ... are you sure this is what is required?

Also missisng is the voltage you will be using.

Typically, a circuit of 120 volts at 20 amps is 2400 watts while 240 volts at 20 amps is 4800 watts. Either circuit would run on number 12 wire protected by a 20 amp breaker (single or double pole). You want to service a 10,000 watt load.

I am not a electrical engineer ... I think you should review the material that came with your shower and follow the manufacturers recommendation. Please read on ...

Number 8 wire should be good for 50 amp capacity. 50A X 240V = 12,000 watts. However, the distance the wire must run is also a consideration.

If this were my installation, I would beef the wire up to the next size. i.e., if the manufacturer says #8 wire, I would use #6 wire

Other things you should consider is whether the installation requires a GFI or other special breaker and special shut off switch and its location.

I hope to have steered you in the proper direction ...

What braker for 240 volts 500 watts 2-1 amps


if you are running a new circuit for this one heater than a simple 2-pole 15 amp breaker will do fine, it is also acceptable to use a 2-pole 20 amp breaker, as long as you are in the united states. since you have such a small unit you can put 7 of these heaters on one 20 amp breaker.

Compressor causes 20 amp breaker to trip.


If I did the math correctly, 5.5 HP is right at the boarderline of 20 amps, particularly for an older machine that has some deteriorating electronics.

What to do? Can you reconfig the motor to run on 220 Volts??? It would then run on 1/2 the amps.

If you have a dedicated 120 line for this compressor now ... all you have to do to change that to 220 is change the breaker (I presume you have a vacant slot to do this). Find the "neutral" for that wire (white) ane make it the "red" for your compressor line ... (and mark it as such for your future behefit) change the outlet from 110 V 20 A to 220 V 20 A. Both lines will run on #12 with G wire.

If you dont have a slot, you could change one of your standard slots to a "piggy back" remodeling style breaker (has two breakers in one slot). This will free up one slot in your panel for the new 220 (double pole) breaker.

Let me know what you think

A diagram of how to wire a 220 volt outlet from two 110 volt outlets.


You can't really do that. The two 110 outlets probably come for the same 'leg' of the 240. If you check them with a meter, there will be '0' volts between the two hot wires. So, they have the same 'potential'. You need a regular 240 volt circuit from a double pole breaker that is rated for the wire size that it's feeding. 20 amp-#12 ; 30 amp- #10 etc.

Problem wiring 240amp baseboard heaters


12 gauge wire sounds under sized for the application. And 20 amp 240 v breakers might be sufficient if you where wiring the heaters separately. But be sure that your wiring is not romex - because romex is an insulator and is not permitted in conduit. I would suggest that you up size your wire to 10 guage and your breaker to 30 amp as well. Then double check your heater wiring connections to insure that they're wired the same throughout.
