Grounding an enlarger
I'm looking at setting up a darkroom in one of two bathrooms in a
house I'm renting. The larger bathroom does not have grounded outlets but the smaller one does. Up to now I've used rental darkrooms and haven't paid any attention to the electrical requirements of enlargers. My questions a 1) Are decent medium format enlargers available that don't have 3-pronged, grounded plugs? 2) Any ideas for safely grounding an enlarger without replacing the outlets? I don't plan on doing anything that will get me electrocuted... |

I don't plan on doing anything that will get me electrocuted... Not only should the outlet be grounded, it should have a GFI (ground fault interrupter) circuit. This is required by code in all new bathrooms, etc. |

I'm looking at setting up a darkroom in one of two bathrooms in a house I'm renting. [Grounding] From a safety viewpoint a ground-fault interrupter is mandatory. All outlets in a room with a water supply should have GFI's installed: bathroom; kitchen; laundry room; outdoor outlets; garage .... When you install GFI outlets they will be three-prong. If you don't have a ground in your house wiring then have one installed for the above mentioned rooms (at the least). If the enlarger does not have a 3 prong cord then you should install one. Connect the ground wire to metal where the cord makes ingress: lamp housing; frame; motor box; or baseboard. Make sure all metal parts of the enlarger are grounded, check with an ohmmeter from the ground lug of the power cord to _all_ exposed metal parts (within reason - lensboards, aperture rings and the like can be ignored). I don't plan on doing anything that will get me electrocuted... Everybody who ever died of electrocution made the same claim. -- Nicholas O.
